Societal Challenges Facing the Future of Photonics

The Photonics contribution to modern society is impressive but not always very

visible. The unique properties of light (colors, speed) together with the recently

developed new technologies allows the user of photonic components to bring

innovative products in end markets that go beyond the national borders. Photonics is

science and technology and includes the study of the generation, propagation,

modulation, signal processing, switching, amplification, detection and sensing of

light.

Photonics is denoted a Key Enabling Technology (KET) by the EU and also

adopted by the Dutch top sector High Tech Systems and Materials (HTSM). Being a

basic technology it provides photonic components that allow innovative solutions in a wide field of applications and contributes directly in search for solutions for the

grand societal challenges of our time:

• In healthcare by radical new approaches moving from current, cost-intensive

treatment after onset of a disease, to the detection and prevention at the earliest

possible stage by new (hand held photonics based) diagnostic instruments, which allows to bring these new tools critical care as well as perform remote diagnostics.

• In energy saving (―green photonics‖) by the introduction of very efficient lightsources, (O)LEDs, and energy generation by highly efficient solar cells.

Emerging Biomedical Sensing Technologies and Their Applications

The ongoing mergence of the 20th century revolution in information technology

with the 21st century revolution in biotechnology poses considerable demand for

new sensors, in particular new biomedical sensors. Currently, the recent advances in

the microelectronics industry, the availability of advanced micro-fabrication

technologies down to the micro and nano-scale, and inexpensive signal processing

systems have made the development of a variety of novel biomedical sensors

possible.

A good indication of that demand is the growing use of personal monitoring devices

such as glucose sensors for diabetics or the recently developed sensors for HIV

detection. Biomedical sensors can also make medical care more personal and

tailored to the individual needs of a patient. In the near future, a treatment procedure

could be adjusted to address a patient‘s unique metabolism and biological rhythms.

For example, the dose of a drug could be correctly determined in order to optimize

the healing process and minimize its side effects. In addition, biomedical sensors

will enable a broad range of medical services at a patient‘s home using a variety of

systems that employ a personal computer and the Internet. One may envision a

dedicated home-based analytical diagnostic system interfaced with a computer that

could monitor and store medical data over the lifetime of the person. In such a case,

specialized application software would be capable of recognizing incoming health

problems and could notify a person in advance of her or his health conditions.

Complementary English /1/

A modern biomedical sensor is a device which consists of a biologically or

biophysically-derived sensing element integrated with a physical transducer that

transforms a measure and into an output signal. The requirements for any good

biomedical sensor are specificity or the ability to pick out one parameter without

interference of the other parameters, sensitivity or the capability to measure small

changes in a given measure and, accuracy or closeness to the true measurement,

time response, biocompatibility, aging characteristics, size, ruggedness and

robustness, and low cost. In addition, the sensor must have compatibility with the

chemical, optical, optoelectronic, or electronic integrated circuit (IC) technology.

The above listed features have been researched comprehensively over the last two

decades and critical knowledge has been accumulated and the challenges have been

identified. One may claim that the biomedical sensor field has matured enough to be

poised for commercial success. In this paper, an overview of three of the primary

biomedical sensor technologies; electro-chemical, optical and acoustic are discussed

along with many of the biomedical applications.

About $20 billion per year are spent for analytical testing worldwide. Specialized

laboratories located away from a patient, doctor, or hospital perform nearly all of the

testing causing significant time delays in reporting results. Modern biomedical

sensors developed with advanced micro-fabrication and signal processing techniques

are becoming inexpensive, accurate, and reliable and, with an average detection time

on the order of a few minutes, can significantly reduce the delay time as well as

bring the testing to doctor‘s offices and patient‘s homes. As a result, the wide use of

biomedical sensors may lead to more individualized health care services that will be

tailored for the needs of a patient and will match a specific genotype. Indeed, one

may envision using biomedical sensors for optimizing drug doses, monitoring the

effectiveness of treatments, and monitoring health conditions over person‘s life time.

In addition to decreased time delays, miniaturization of biomedical sensors and

integration with micro-fluidic devices is yielding advanced analytical micro-systems

such as a BioChemLab-on-a-Chip. Integration of several sensors on a single

substrate produces transducer arrays. A few recent examples include electronic

noses and tongues that are capable of performing multi-measure and detection in a

few minutes.

Part Two: Grammar

Clause, Phrase & Sentence

The basic unit of English grammar is the clause:

A clause is a group of words that DOES contain both a subject and a verb.

[An unlucky student almost lost a 17th century violin worth almost £200,000] [when he left it in the waiting room of a London station.]

[William Brown inherited the 1698 Stradivarius violin from his mother] [and had just had it valued by a London dealer at £180,000.]

Clauses are made up of phrases:

A phrase is a group of words that DOES NOT contain a subject and a verb. For example, a prepositional phrase functions as a modifier and only consists of a preposition, its object, and any modifiers the object may have.

[An unlucky student] + [almost lost] + [a 17th century violin worth almost £200,000]

[when] + [he] + [left] + [it] + [in the waiting room of a London station.] [William Brown] + [inherited] + [the 1698 Stradivarius violin] + [from his

mother]

[and] [had just had it valued] + [by a London dealer] + [at £180,000.]

We can join two or more clauses together to make sentences.

A sentence is a group of words that contains a subject, a verb and a complete meaning.

An unlucky student almost lost a 17th century violin worth almost £200,000 when he left it in the waiting room of a London station.

William Brown inherited the 1698 Stradivarius violin from his mother and had just had it valued by a London dealer at £180,000.

All clauses in English have at least two parts: a noun phrase and a verb phrase:

Noun phrase (subject) Verb phrase

The children laughed

All the people in the bus were watching

21

Page 12: Fundamentals of Applied Photonics · Photonics is one of the most important key technologies for the 21st century enabling solutions for the societal challenges the world is facing.

Complementary English /1/

But most clauses have more than two parts:

Noun phrase (subject) Verb phrase

The children laughed

John wanted a new bicycle

All of the girls are learning English

This soup tastes awful

Mary and the family were driving to Madrid

She put the flowers in a vase

The first noun phrase is the subject of the sentence:

The children laughed.

John wanted a new bicycle.

All the girls are learning English.

She put the flowers in the vase.

English clauses always have a subject:

His father has just retired. Was a teacher. He was a teacher.

I‘m waiting for my wife. Is late. She is late.

… except for the imperative which is used to give orders:

Stop!

Go away.

… and for "soft imperatives" like invitations and requests:

Please come to dinner tomorrow.

Play it again please.

If we have no other subject we use "there" or "it" as subject. We call this a ‗dummy subject‘:

There were twenty people at the meeting..

There will be an eclipse of the moon tonight.

It‘s a lovely day. It‘s nearly one o‘clock.

I have toothache. It hurts a lot.

22

Page 13: Fundamentals of Applied Photonics · Photonics is one of the most important key technologies for the 21st century enabling solutions for the societal challenges the world is facing.

Complementary English /1/

Simple sentences:

A simple sentence has only one clause:

The children were laughing.

John wanted a new bicycle.

All the girls are learning English.

Compound sentences:

A compound sentence has two or more clauses: (We stayed behind) and (finished the job)

(We stayed behind) and (finished the job), then (we went home)

The clauses in a compound sentence are joined by coordinating conjunctions: John shouted and everybody waved.

We looked everywhere but we couldn‘t find him.

They are coming by car so they should be here soon.

The common coordinating conjunctions are: and – but – or – nor – so – then – yet

Complex sentences: A complex sentence has a main clause and one or more adverbial clauses. Adverbial clauses usually come after the main clause:

Her father died when she was very young

Her father died (main clause)

when (subordinating conjunction)

she was very young (adverbial clause)

She had a difficult childhood because her father died when she was very young. She had a difficult childhood (main clause)

because (subordinating conjunction)

her father died (adverbial clause)

when (subordinating conjunction)

she was very young (adverbial clause).

Some subordinate clauses can come in front of the main clause:

Although a few snakes are dangerous most of them are quite harmless Although (subordinating conjunction)

some snakes are dangerous (adverbial clause)

most of them are harmless (main clause).

A sentence can contain both subordinate and coordinate clauses:

Although she has always lived in France, she speaks fluent English because her mother was American and her father was Nigerian
