  • Introduction - PAX5700 PolarimeterThe PAX5700 Series polarimeter system is a flexible and powerful polarization analysissystem based on our modular TXP5000 platform (see page 444). This polarimeter system isdesigned for different applications ranging from classic polarization measurements tocomplex tasks like evaluating optical components with the Jones or Mueller matrixalgorithm. It is also well suited for determining the extinction ratio (ER) of polarization-maintaining fibers (PMF) and for alignment of PMF to laser modules. Furthermore, acomplete PMD and PDL analysis system can be built by combining the PAX5700 (ourDPC5500 deterministic polarization controller) and our ECL5000D tunable laser source.The PAX5700 series is specifically engineered for accurate measurements of polarization-related effects for high dynamic power ranges in the 400 to 1700nm spectral range. It isavailable in two versions, one with an intergrated sensor (PAX5720 series) for fiber-basedapplications and the other as a module with an external sensor head (PAX5710 series) forfree-space and fiber-based optical systems. Both versions are terminating; in other words,they do not have an output for theincident light.

    How it WorksThe optical unit of a PAX5700measurement sensor consists of arotating quarter-wave plate, a fixedpolarizer, and a photodiode (see Figure 1). The wave plate transformsthe input polarization depending onthe actual rotating angle. Then, thepolarizer only transmits the portion of light that has its polarization parallel to thetransmission axis. As a result, the polarization modulation is converted into an amplitudemodulation. The photodetector supplies a current that is proportional to the optical power.A Fourier transformation is used to accurately calculate both the state of polarization (SOP)as well as the degree of polarization (DOP).

    SOP and DOP MeasurementsThe PAX5700 analyzes the state of polarization and the degree of polarization of opticalsignals in either free-space or in optical fibers. The resulting data can be viewed using thegraphical user interface that issupplied with each PAX unit. Thestate of the input polarization iscompletely characterized by differentrepresentations. As can be seen inFigure 2, the polarization data ispresented in a number of forms: on the Poincar sphere, as Stokesparameters, or as a polarization ellipse with the handedness noted. The degree of polarization and the total optical power are also provided.

    PAX5700 Series Polarimeters Page 2 of 3Long-Term Polarization MeasurementsAnother standard feature is the scope mode, whichlooks similar to an oscilloscope display. Thepolarization can be examined continuously over timeor initiated with a software or hardware trigger signal.The number of data points to be acquired can bechosen by the user. Another feature is the pre-triggerfunction, which can be activated in each triggermode. A user-configurable number of samples arestored in a ring buffer until the trigger pulse is given.All acquired data before and after the trigger pulse aredisplayed in a diagram. Therefore, a real-timemonitoring of the system's polarization behavior canbe realized with the PAX measurement system. Themeasured data can be stored in an ASCII format file(CSV). The data file contents can be viewed with anytext editor and can be further processed using third-party software packages such as MathCAD,Mathematica, or Excel.

    Software FeaturesThe software for the PAX system includes drivers forLabVIEW, LabWindows/CVI, MSVC, andBorland C. These drivers enable you to write yourown applications to adapt the polarimeter into acomplete optical setup. Included in the software arefeatures specifically geared for extinction ratio (ER)measurements (see below).

    System ConfigurationsDue to its modular design and the various modelsavailable, the PAX system is an ideal tool for varioustypes of polarization-related measurement tasks inR&D laboratories as well as for final inspection inmanufacturing. The PAX5700 series can be used forfree-space and fiber-based applications covering the400 to 1700nm wavelength range. See the followingpage for ordering information.

    The PAX5710 consists of a TXP compatible module and an externalpolarization measurement sensor. The PAN5710 external measurement sensorfacilitates polarization analysis in free-space setups. It can be easily mountedto optical benches using the M4 or #8-32 mounting hole provided on thebottom surface of the head. It is also compatible with our extensive line of30mm cage system components. The opticallight field to be measured shouldenter the aperture of the sensornearly perpendicular to the frontpanel. The beam diameter should bebelow 3mm to guarantee that all ofthe light reaches the detector. Allsensors are supplied with a fibercollimator for FC/PC optical cablesto allow polarization measurementson fiber-based systems, or you maychoose to use the PAX5720, whichis dedicated to fiber-basedmeasurements.

    Extinction Ratio Measurement on Polarization Maintaining FibersExtinction ratio (ER) is a key qualifier of polarization-maintaining (PM)fibers and PM couplings. Using the standard features built into the PAXsoftware, ER measurements can be made quickly and reliably in the 0 to45dB range.

    The measured ER parameter refers to the PMF directly connected to thepolarimeter input.

    The easiest measurement technique is to find the maximum expansion of thepolarization ellipse compared to the ideal linear state. Since this expansion isdependent on the fiber stress, a lot of values have to be recorded while thefiber is stressed, pulled, or a wavelength scan is performed.

    This technique requires the highest accuracy in the measurement of theellipticity angle. With a very high ER, the setup is prone to measurementinaccuracies. The PAX5700 uses an optimized algorithm to mitigate thisissue. The data collected from fiber stressing is used to fit a circle on thePoincar sphere. The radius of the circle, expressed in degrees, isrepresentative of the maximum expansion of the polarization ellipse.

    Only the relative polarization measurement accuracy determines the ER measurement error, since the shift of the circle to any position on thePoincar sphere is irrelevant as long as the size of the circle remainsunchanged. Errorsresulting from poorly orangle-polished fibershave no influence on thefinal value. Only the ERof the stressed fibersegment is measured.

    The ER measurementon PMF is integrated inthe PAX5700 software,along with allpolarimeter-relatedfunctions.

    from the polarimeter and drives the non-deterministic SOP controller,which is comprised of a multitude of piezoelectric based fibersqueezers. A simple yet robust calibration algorithm accounts for theinherent nonlinearities in the piezoelectric elements and allows foraccurate and stable deterministic SOP control.

    This facilitates SOP control at a user-defined location in theoptical system such that the SOP can be varied to accurately andprecisely follow a prescribed path on the Poincar sphere (seeFigure 1).

    Comparison to Existing Systems The DPC5500 eliminates the inadequacies of mostcommercially available SOP controllers whose output SOPdepends on the input SOP. Any input SOP change willimplicitly lead to a corresponding output SOP rotation. Inaddition, most commercial high-speed SOP controllers are trial and error controllers and suffer from drift andhysteresis effects. They are non-deterministic and aredependent on environmental and prior conditions. This all-fiber technology provides deterministic control with verylow insertion loss. The desired SOP may either be defined via its azimuth/ellipticity parameters or its corresponding Stokes values, which are graphically defined by a point on thePoincar sphere or electronically defined by supplying afeedback signal from a control loop.

    Introduction - DPC5500The DPC5500, an in-line deterministicpolarization controller for the TXP5000 systems,combines deterministic state of polarization control,high speed, low loss, and high accuracy in a uniqueall-fiber-based solution. It is a versatile polarizationcontrol solution that may be utilized in manyapplications, ranging from R&D to industrialapplications. The polarization controller isavailable as a module (DPC5500) for the TXPmainframe (page 444) or as a complete benchtopunit including a preconfigured PC (DPC5500-TSeries).

    The DPC5500 is based on our high-speed, low-loss IPM5300 polarimeter technology and anon-deterministic state of polarization (SOP)controller. A digital signal processor (DSP)produces a feedback signal from the polarimeterto drive the fiber squeezer-based state ofpolarization controller. The DPC5500 is idealfor applications that require precise deterministiccontrol or locking of a SOP.Software modulesfor electronic SOP control, SOP tracing on thePoincar sphere and SOP scrambling areavailable for specific application.

    How It WorksCentral to the DPC5500 is a DSP, which enableshigh-speed control and locking of the SOP. TheDSP monitors the polarization feedback signal

    SOP ScramblerThe systems also includes a SOP Scrambler, which can be used to depolarize asource to minimize PDG in fiber networks, to eliminate polarization dependenciesof fiber optic sensors, or to perform PDL measurements.

    The SOP Scrambler provides six modes of operation:

    IPM5300 In-Line Polarimeter Page 1 of 2Introduction - IPM5300 Fast In-Line PolarimeterThe IPM5300 fiber optic polarimeter module enables high-speed measurements of the state ofpolarization (SOP). The in-line fiber design has an insertion loss of less than 0.6dB, a dynamic range of45dBm, and an accuracy of 0.25 on the Poincar sphere with a sampling rate of 1MHz. TheIPM5300 series is available as a module for the TXP mainframe (page 444) or as a complete benchtopunit including preconfigured PC (IPM5300-T series).

    This all fiber polarimeter is based on patented FBG technology. It provides a novel combinationof in-line polarimetric measurement, low insertion loss, high speed, and accuracy that enables

    unprecedented measurement control of the SOP in fiber optic applications.

    How it WorksThe IPM5300 polarimeter is designed as an in-linepolarimeter that utilizes a series of custom fiber Bragggratings (FBGs). Figure 1 shows the optical schematicof the polarimeter module. The device uses two pairsof FBGs, whose reflectivity is polarization dependentto direct very small percentages of the transmittedoptical power to four detectors. A /4 fiber wave plateis positioned between the two pairs of FBGs toproduce the two additional elliptical states ofpolarization that are required for a full analysis of anarbitrary state of polarization.

    The IPM5300 overcomes the limitations of other fiber-based in-line polarimeter designs by eliminating the need to use tap couplers,which exhibit temperature and wavelength sensitivity. The FBG approach offers superior performance; it provides an extremely broadwavelength range (1200-1700nm) as well as highly accurate SOP and DOP measurements.

    Polarimeter FunctionalityAll four Stokes values, which fully characterize a SOP, are provided either as analogoutput voltages or as digital values via either an Ethernet connection (TXP5016chassis), or a USB port (TXP5004 chassis). The SOP measurement can be controlledvia an external trigger function, thus allowing the synchronization of the IPM5300with other devices. The 1MHz update rate applies to the fully characterized SOPmeasurement. With its broad wavelength range, low loss, high speed, and accuracy,there are no other commercially available polarimeters with these combined features.Our polarization control capabilities are presented on the following page.

    An example of the measurement capability of theIPM5300 polarimeter is demonstrated in the datashown to the right. The experimental setup isdepicted in Figure 3. A fiber-pigtailed laser wasused as the input to the polarization controller.The signal from the controller was input to theIPM5300 which was installed in a TXP chassisand controlled via a local computer. The acquireddata included the state of polarization (SOP), thechange in the SOP, the power, and the degree ofpolarization (DOP). This data is shown in Figures2 and 3.

    The piezoelectric-based polarization controller wascontrolled with a square wave signal at 2kHz tocause quick changes in the state of polarizationinto the polarimeter. The induced polarizationchange was 82 on the Poincar sphere. Figure 1ashows the measured Stokes vector elements (S1,S2, and S3), while Figure 1b shows the angulardeviation in the state of polarization on thePoincar sphere. Figure 2 shows the totalmeasured power and the DOP versus time. Oneaspect of the data that is clearly evident in Figure1 is the ripple. The polarimeter, with a dataacqisition rate of 106 samples per second,accurately measures the SOP as the controllerchanges polarization (Figure 1a). The ripple in thedata has a period of 20sec (50kHz), which iseasily resolved by the polarimeter. This rippledisplays true variation in the SOP caused byvariations in the mechanical stress on the fiberdue to a 50kHz mechanical resonance in thepiezo controller.

    Despite the resonance, the measured opticalpower and the DOP was constant as thepolarization was changed. The deviations in thedata are at the measurement uncertainties of thepolarimeter,

    Fiber Polarization Controller

    If your application includes single mode fiber and requires linearlypolarized light, the FPC Series Polarization Controllers can beeasily implemented to convert elliptically polarized light in a singlemode fiber into another state of polarization, including linearlypolarized light. This polarization conversion is acheived by loadingthe three paddles with a prescribed number of fiber loops andadjusting their positions to control the output polarization state.

    These polarization controllers utilize stress-induced birefringence tocreate three independent fractional wave plates to alter thepolarization of the transmitted light in the single mode fiber bylooping the fiber into three independent spools.

    The amount of birefringence induced in the fiber is a function ofthe fiber cladding diameter, the spool diameter (fixed), the numberof fiber loops per spool, and the wavelength of the light.

    The ERM100 is an Extinction Ratio Meterbased on the rotating polarizer technique. Thisbenchtop device offers a fast and simple way tomeasure the ER of PM fibers. It is an easy-to-usedevice that may be utilized in many applicationswhere the alignment of polarization maintainingfibers is required.

    How it works

    The ERM100 Extinction Ratio Meter contains a rotatingpolarizer followed by a detector, which generates a photocurrent.In general, this photocurrent will be a sinusoidal function in timewith a DC offset. By simultaneously analyzing the DC offset andthe depth of modulation, the meter is able to determine the degreeto which the light field is linearly polarized, thereby yielding theextinction ratio (ER).

    PM Alignment Application

    The ERM100 Extinction Ratio Meter can be used to align the axisof a PM fiber with the polarization axis of the linearly polarizedincident light. This process is not trivial because the PM fiberexhibits stress induced birefringence that affects the ellipticity of thepolarization state outputted from the fiber. As a result, properalignment of the fiber axis requires that a time varying stress beapplied to the PM fiber while maximizing the extinction ratio of thetransmitted light. As the alignment between the fiber axis and thepolarization axis of the incident light field is improved, the effect ofthe time varying stress will be reduced, thereby stabilizing the ER.At this point, the axis of the PM fiber will be optimally aligned withthe polarization axis of the linearly polarized incident light.

    Benefits

    This benchtop instrument is an easyto use measurement device for anykind of PM fiber alignmentapplication. A set of buttons and theLC display on the front panel allowa quick adjustment andmeasurement procedure. Any PMalignment task can be performedefficiently.

    The ERM100 is factory calibratedand provides the ER, themisalignment angle, and the power.It can also be controlled via USB.Drivers for LabVIEW,LabWindows/CVI, MSVC,and Borland C are included.

    PMD / PDL Measurement Systems (Page 1 of 4)

    Introduction - PMD5000The PMD5000 Series is a high-performance Polarization Mode Dispersion (PMD)testing system based on the Jones Matrix Eigen Analysis. The modular design offersa unique flexibility and adaptivity, making this system ideal for all kinds ofpolarization related measurements. It is especially useful for PMD analysis on broadband and narrowband components, optical fibers, and installed opticalnetwork; these systems are capable of determining Polarization Dependent Loss(PDL) and Polarization Dependent Gain (PDG). Efficient PMD measurements ofcomplex optical networks as well as PMD monitoring of dark channels are otherapplications that benefit from the ability to control a single transmitter unit andmultiple receiver units at different locations via one remote computer.

    The transmitter module of the PMD5000 Series consists of a tunable laser sourceand a polarization controller. For the analyzer, different high performancepolarimeter modules are available, which allow the system to be optimized for aparticular application. If the system is being used with a split transmitter analyzerconfiguration, the unit can be controlled remotely via TCP/IP, Ethernet, or WLAN.The system is based on the TXP architecture and offers full compatibility. See page444 for an overview of the different configuration options. For more detailedinformation, please contact our tech support team.

    ModularityThe PMD5000 measurement system includes theTXP5016 mainframe (See page 444) and iscontrolled by an external computer via Ethernetor TCP/IP. The TXP architechture allows aseparation of the transmitter and receiver unitsinto two mainframes. The mainframes andcontrol PC can be connected to the Local AreaNetwork (LAN) and are not necessarily tied to asingle location.The transmitter unit consists of the ECL5000DSeries Tunable Laser and the DPC5500 SeriesDeterministic Polarization Controller, whichadjusts the necessary states of polarization. Thesemodules are key components for the Jones MatrixEigenanalysis (JME). (Refer to the PMDapplication note on page 986 for moreinformation).

    For the analyzer unit, either the IPM5300 SeriesHigh Speed In-Line Polarimeter or the PAX5720Series High Dynamic Range Polarimeter may be selected, depending on the applicationrequirements.

    The fast IPM5300 is especially suited for PMDmeasurements on fibers with rapid changes inenvironmental conditions, which can affect thePMD, and therefore, faster measurement speeds(PMD5000FIN Series) are required. The highdynamic power range of the PAX5720 Series isrequired for Differential Group Delay (DGD)measurements of components with bandpasscharacteristics.

    A preconfigured laptop is included with the system. The software includesall features to analyze the PMD and PDL of fiber and optical components.It is intuitive and allows extensive analysis of the measured data set.

    Application Note: PMD Measurement Polarization Mode DispersionPolarization Mode Dispersion (PMD) originates from thepolarization dependency of an optical signal's propagation speed,which results in a delay in the arrival time of a bit stream fororthogonally launched polarization states and may lead to biterrors. For a given wavelength, the maximum delay between allpairs of orthogonal polarization states at a given time is called theDifferential Group Delay, DGD (see Figure 1). DGD ismeasured in picoseconds (ps). The polarization states associatedwith the fastest and slowest speeds are called Principal States ofPolarization (PSP). In general, the PSPs are not associated withthe fast and slow axes (the Eigen-Polarizations) of a birefringentcomponent.

    DGD is the primary measurement parameter for all PMD meters. The measurement of the DGD involves the determination of a phasechange (arrival time difference) for a given frequency (wavelength) change. For a Jones Matrix Eigenanalysis, the polarimetric transferfunction (the Jones Matrix) must be determined at two different wavelengths. The changes in the phases of the two Jones matrices dividedby the wavelength difference (step size) yields the DGD value.

    The PMD5000 is ideally suited for characterizing DGD / PMD devices with random mode coupling, such as optical fibers, by using theJones Matrix Eigenanalysis (JME) method. The JME method is the only technique providing wavelength dependent information aboutthe DGD and the PSP. It is also the only method that shows agreement between the measured DGD histogram and the theoreticalMaxwell distribution.

    Jones Matrix EigenanalysisThe Jones Matrix Eigenanalysis (JME) provides the most comprehensive information about fiber links and active components. Besides theDGD over wavelength and the PMD value, the JME also returns the second order PMD as well as PDL and measures insertion loss vs.wavelength. In general, monochromatic light with different input polarizations is fed into the optical device, and the polarizations responsesare measured. A convenient way to measure the Jones Matrix was presented by B.L. Heffner.1) Linearly polarized light enters the opticalelement parallel to the x-axis, parallel to the y-axis, and parallel to the bisector of the angle between the positive x- and y-axes. The threelinear input states and the three corresponding polarization output states are used to calculate the 2x2 complex Jones matrix. In a puremathematical sense, only two pairs of input and output states are needed to calculate a 2x2 matrix; however, since optical elements featureEigenpolarization states for which the inputpolarization is not transformed (i.e. the outputpolarization is equal to the input polarization),a third unique input polarization is needed.

    PMD in Optical FiberFibers may be modeled as a collection of manyinfinitesimally small fiber sections, each of whichhave a different birefringence and Eigen-polarization axes (see Figure 2). Thermal andmechanical stresses will change the polarizationproperties of these sections. The large number of sections, the randomness in the transformation properties, and environmentalsensitivities require a statistical analysis to account for the DGD behavior fully. In a long length of fiber, the DGD (either as a function oftime at fixed wavelength or as a function of wavelength at a fixed time) has a Maxwell distribution. The average of the DGD distributionis defined by the ITU standard bodies as the PMD value. Therefore, PMD is independent of the time and wavelength range.

    PMD in Fiber Components

    Fiber optic components differ from long lengths of fiber in their thermal and mechanical sensitivity of DGD / PMD. The fixed opticalelements integrated in the components are significantly less sensitive to environmental conditions. Fiber optic components have DGDvalues that are nearly fixed with respect to wavelength. A DGD measurement instrument would therefore produce a normal (Gaussian)distribution. Depending on the test instrument, the width of the distribution is determined by the instrument's performance and not theintrinsic randomness of the polarization modes throughout the component. As in the fiber PMD, the average value of the distribution isthe PMD value that quantifies the amount of delay generated by the component. For some fiber optic components, DGD/PMD cannotbe measured using the same procedure as those used for systems with random mode coupling. For example, DEMUX filters, with theirnarrow pass bands, do not allow relatively large frequency steps for high accuracy DGD measurements. Therefore, these filter componentsrequire special measurement attention. The PMD5000 Series Polarization Measurement System is designed for analyzing narrowbandwidth components and fiber networks [i.e. single components like Fiber Bragg Gratings (fbg) as well as single channels of a complexoptical network with multiplexers and active components (like EDFAs)].

    Thorlabs' Zero-Order Wave Plates are built by combining two multi-order quartz waveplates with an optical path length difference of /4 or /2. By aligning the fast axis ofone plate with the slow axis of the other, the net result is a compound retarder whoseexact retardance is the difference between each plate's individual retardence. Compoundzero-order wave plates offer a substantially lower dependence on temperature andwavelength than multi-order wave plates.

    These zero-order wave plates are constructed by sandwiching an etched stainless steelspacing ring between the two multi-order wave plates and epoxying the entire assemblyinto an anodized aluminum housing. The epoxy is only applied outside of the clearaperture in order to prevent the damage threshold from decreasing. The wave platehousing is engraved with a line indicating the orientation of the fast axis of the waveplate, as well as with text stating whether it is a /4 or /2 wave plate and thewavelength for which the wave plate was designed. The typical thickness of a zero-orderwave plate is around 2mm but can vary from part to part.

    A Soleil-Babinet Compensator is a continuously variable zero-order retarder (wave plate) that can be used over a broad spectral range. Thevariable retardance is achieved by adjusting the position of a long birefringent wedge with respect to a short fixed birefringent wedge. Thewedge angle and fast axis orientation is the same for both wedges so that the retardance is uniform across the entire clear aperture of theSoleil-Babinet compensator. The orientation of the fast axis of the wedge is engraved on the housing of the Soleil-Babinet compensator. Acompensator plate is attached to the fixed wedge with its fast axis orthogonal to both the fast axis of the wedges and the propagationdirection of the light. When the long birefringent wedge is positioned such that the total thickness of the two stacked wedges is equal tothe thickness of the compensator plate, the net retardance of light passing through the Soleil-Babinet compensator will be zero. Theposition of the long wedge can then be adjusted with a precision micrometer in order to create a retardance of up to 2 in the transmittedbeam of light. The micrometer has a digital readout with a resolution of 0.001mm for ease of use. The fast axis orientation of the Soleil-Babinet compensator can be continually adjusted since the entire assembly is mounted on a rotation stage. The rotation stage has aVernier scale for increased resolution. In addition, the rotational mount has detent positions in 45 increments so that the fast axis can beefficiently switched between parallel and 45 orientations. Finally, the entire assembly can be tipped or tilted with two fine pitchedadjustment screws and can be mounted on a TR series post via one of six counterbored #8-32 (M4) holes in the kinematic mount.

    SBC-COMM is an accessories package that allows the digital micrometer to be connected to a computer via an RS-232 communicationsport. In addition to the cables and connectors, SBC-COMM includes a CD with micrometer LabVIEW drivers and a stand-alonemicrometer program. Once the Soleil-Babinet compensator is calibrated at a single wavelength, the software can output the micrometerposition required for any retardance at any wavelength within the operating range.

    The calibration procedure, which is necessary for calculating the position of the micrometer for a given retardance at a specifiedwavelength (whether the SBC-COMM packaged is used or not) is explained in the manual. The procedure is easy to complete but doesrequire additional equipment, since the Soleil-Babinet compensator must be placed between two crossed polarizers and illuminated withcoherent monochromatic light at a known wavelength. The manual is available at www.thorlabs.com.

    The Glan-Taylor Calcite Polarizer provides extremely pure linear polarization(100,000:1) for broadband sources. The input and output faces are polishedto a laser quality 20-10 scratch-dig surface finish to minimize scattering of thetransmitted P polarization component of the laser beam or light field. The Spolarization component is reflected through a 68 angle and exits the polarizerthrough one of the two side ports, which are pad polished. For high-powerapplications, see the Glan-Laser Polarizer.

    The Glan-Laser Calcite Polarizer is a Glan-Taylor polarizer that is specificallydesigned to deal with high energy laser light. These polarizers are manufacturedfrom only select portions of the calcite crystal, which must pass a laser scatteringsensitivity test. Like our Glan-Taylor Prisms, these prisms are ideal for applicationsrequiring extremely high polarization purity (100,000:1), high damage threshold(500MW/cm2), and a broad wavelength range (350nm-2.3m). Two polished sideexit ports are provided to allow bidirectional use of the prism polarizer. These sideports also ensure that the rejected light from high-power lasers can safely exit thepolarizer.

    DepolarizersDepolarizers convert a polarized beam of light into a pseudo-random polarizedbeam of light. The pseudo-random polarization of the output beam may be suitableto use with polarization-sensitive devices when linearly polarized light is not.

    Our depolarizers are optically contacted and AR coated for high power operation.

    Wedge DepolarizersA variation in retardance across the aperture is created by the wedge-shapedcrystalline quartz optic to scramble the polarization. A fused silica wedge iscemented to the quartz wedge to compensate for beam deviation. Wedgedepolarizers are achromatic and can be used with any input beam.

    Lyot DepolarizersLyot depolarizers consist of two quartz wave plates, one being exactly twice thethickness of the other and are assembled with their optic axes 45 apart. Thiscombination creates various degrees of elliptical polarization as a functionof wavelength, and therefore, Lyot depolarizers cannot be used withmonochromatic beams.
