• Example shows a sine-bend, defined by the width of the waveguide and the distance between the input and output in vertical and horizontal direction

15

OptoDesigner 5, chip and mask layout

Some examples of elements in the standard library:

CurvedWire, Polygon, RectangleRounded, Straight, StraightOffset, Wire, WireRoute, Yblunt, BendEllipse, Circle, CircleSegment, Donut, Ellipse, EllipseSegment, EllipseSliced, Bend, BendCosine, BendEuler, BendPolar, BendS, BendSine, …

Any shape you can describe mathematically can be used as well


• Photonics elements are combined into devices

• Example shows a Mach-Zehnder interferometer, created out of 4 (or 12) elements

• Connectivity is important, in case you want to make changes. For instance to introduce a phase (read length) difference between the two arms

16

Snapshot of devices in the photonics library:

DirectionalCoupler, MMI1xN, MMI2xN, MMIMxN, StarCoupler, StarCouplerMxN, ModeSplitter, Sjunction, StarBase, ArcLens, EllipticalLens, HyperbolicLens, SpiralSegment, SpiralSegmentInOut, …

If you create your own device you can easily add it to the library

OptoDesigner 5, chip and mask layout


Generic (EDA) scripting languagesdon’t understand photonics and are inefficient

Example of the description of a sine-bend taken from a Cadence Virtuoso (SKILL) p-cell as used in a silicon photonics PDK

Same applies to Mentor Graphics AMPLEOr generic languages like Matlab, Python, Ruby, …


PhoeniX Software’s powerful scriptis very efficient as it has photonics DNA

OptoDesigner supports the generation of script through its user interface and/or direct entry in the editor.

The resulting single script line for the generation of a sine-bend is:

ml::BendSine(cin->[0,0]: wfix(Width), Length, Height);





parameters






relative connectivity






width profile




Several options for the width profile exist: fixed, linearly changing, exponentially changing, parabolicly changingand even arbitrary functionally changing.

And … the conversion of the intended shape to discretized polygons with a user defined maximum error to the idealpath in the final mask file is fully automated!

Note: instead of the built-in sine-bend any arbitrary self defined function can be used as well, like:

ml::CenterPath( cin->[0,0] : {t->t*Length,-0.5*Height*cos(t*pi)}, wfix(Width));

wfix wlin wexp wpar

Ease of design through Photonic Synthesis enabled by PhoeniX Software’s photonic building block platform

27

In integrated photonics there is some emerging standardization in materials and processes, however today it is dynamic and diverse:

• New materials will be introduced• Process changes will happen• Designs being ported from R&D

into volume

Hence the need for a structuredand flexible design environment, focused on manufacturability


Ease of design through Photonic Synthesis enabled by OptoDesigner’s photonic building block platform

Photonics building block:

• Translates design intent into DRC clean layout• Design intent can be either optically or

geometrically defined• Ability to handle wide parameter range• Incorporates process information

Example:Arrayed waveguide grating (AWG),widely used as optical mux/demux



29

From design intent to final mask layout:

• Calculating the required shapes, given the design intent and the fabrication information

• Turning these into polygons, given a maximum allowed path error

• Placing the polygons into the required mask layers, including sizing, inversion, booleanoperations, etc.

• Checking design rules• Exporting mask (GDS2) files

AWG example: from intended waveguide or “logical” design into actual mask or “GDS” design to fabricate with the correct waveguide dimensions (cross section)



Example: optical delay-line, implemented as spiral


• A “90 degree optical hybrid” is a key component for optical receivers

• Purpose is to measure the phase difference between two optical signals, by converting the optical signals into electrical signals representing the Re and Im parts of the complex amplitude difference

• Applied to reconstruct complex phase modulated signals(like DQPSK en 16QAM)



• A “90 degree optical hybrid” building block contains splitters, crossings, combiners, detectors and connecting waveguides

Yohei Sakamaki, Takeshi Kawai, Tetsuro Komukai, Mitsunori Fukutoku, Tomoyoshi Kataoka, Toshio Watanabe, Yuzo Ishii, "Experimental demonstration of multi-degree colorless, directionless, contentionless ROADM for 127-Gbit/s PDM-QPSK transmission system" Opt. Express 19, B1-B11 (2011)

“Monolithically integrated dual-quadrature receiver on InP with 30 nm tunable local oscillator”, Kimchau N. Nguyen et al., OSA 2011, December 2011 / Vol. 19, No. 26 / OPTICS EXPRESS B716




Example: 90 degree hybrid, including 1-symbol delay

The path length difference ∆𝐿 in the 90 degree hybrid Building Block depends on the used photonic technology:

∆𝐿 = 𝜆4 𝑛𝑔

,

where 𝜆 is the wavelength and 𝑛𝑔 is the group index of the used

waveguide.


• The MMI’s, crossings and detectors can be picked from the design library and placed into the layout at the required locations

• As the connecting waveguides are constraint based, special care is required when designing these• Depending on the fabrication technology and waveguide geometry (cross section) the actual

routing needs to be calculated and implemented

• The optical path lengths of the connecting waveguides need tomatch, including a 90degree phase shift, given the positions of the input and output ports of all the individual components



• Matching the waveguides optical path lengths requires• Ability to calculate (or simulate) and use the optical properties of a waveguide (group index)

• Relative connectivity, to solve the netlist of the connecting waveguides between all the components, and to allow for making changes easily

The path length difference ∆L for a 90 degree phase shift is determined by the technology. Therefore, ∆L should not change if the imposed constraints of the Building Blocks changes, such as the distances between its output ports.


gap = 110 umgap = 170 um


• Matching the optical path lengths requires• Ability to calculate (or simulate) and use the optical properties of a waveguide (group index)


Example for silicon photonics technology∆L for 90° phase shift = 0.0922 µm(ng 4.2 @ 1550nm )

Example for InP PIC technology∆L for 90° phase shift = 0.1047 µm(ng 3.7 @ 1550nm)



• Matching optical path lengths requires• Ability to calculate (or simulate) and use the optical properties of a waveguide


Example for silicon photonics technology∆L for 90° phase shift = 0.0922 µm(ng 4.2 @ 1550nm )

Example for InP PIC technology∆L for 90° phase shift = 0.1047 µm(ng 3.7 @ 1550nm)

Drawing waveguides by hand while obtaining these kind of small but critical length differences is impossible

The waveguides need to be automatically implemented, based on technology information and the location of the input and output ports

OptoDesigner with its photonics DNA is the right solution to provide all the required design capabilities

More than 300 designs created and fabricated in MPW’s with our tools in the last 3 years!


PhoeniX Software actively collaboratesby co-founding the PDAFlow foundation in 2013

PDAFlow eco-system: software vendors collaborating to improve design flows


PhoeniX Software is playing a central roleto create more integrated design flows, including EDA oriented

40

In addition to a PhoeniX based design flow

• Centered around (PDAFlow) PDKs and core capabilities of the PhoeniX Software platform

• Enabling schematic capture in a PDA or EDA tool and hand-over to OptoDesignerfor layout implementation, routing and verification (DRC, connectivity)

• Curve handling and layout generation in OptoDesigner and writing to GDS or OA to integrate into EDA tools, like Virtuoso, L-Edit, Pyxis

• Provide additional curve information to support LVS with Calibre


Collaboration and Standardization

PhoeniX Software collaborates with software vendors from photonics and electronics to improve design flows

PhoeniX Software co-founded with Photon Design and Filarete the PDAFlowfoundation, maintaining an open standard for tool interoperability and PDKs


• Most of our customers use OptoDesigner stand-alone for PIC layout• Combination of MPW/external fab users as well as vertically integrated OEMs

• Includes DRC, connectivity checks and access to PDKs (external or internal)

• A part of these customers use our physical simulators• Mainly to support layout generation of functional (WDM, delays, phase matching) photonic structures

• We target simulation/calculation assisted layout generation, to turn design intent into manufacturable layout

• All relevant solvers are available in OptoDesigner

• Some customers create layout in OptoDesigner and import this (by means of a GDS file) into EDA tools• Especially traditionally IC oriented organizations, already making use of EDA mask layout solutions

42

Use case scenarios (1)


• Traditional IC design tools are missing generic photonic elements and devices. There are some example libraries, but for actual design you need to start from scratch• This requires writing extensive scripts for a very large fraction of the design

• And photonics is non-Manhattan and requires all angle design features (location of ports, rotation, smooth curves, connectivity)

• Even when a PDK is available, you will need custom design of photonics• Eg. waveguide optical length matching / WDM components / filtering / …

• IMEC MPW coordinator Amit Khana: “…today 70% of the designs is full custom.”

• OptoDesigner provides all its native built-in photonics layout elements, devices, routing, simulations, …, capabilities stand-alone or in combination with tools from other vendors

• Using OptoDesigner saves time and money and decreases risk• CEA-Leti MPW coordinator Maryse Fournier: “We see directly when the design

is made with PhoeniX: very high quality, ready to fabricate.”

43
