They are extensively used in astronomical cameras, video camcorders and
scanners as well. CMOS image sensors have entered into a strong wave of
sales growth as digital imaging moves into new automotive-safety systems, medical equipment, video security and surveillance networks, human-recognition user interfaces, wearable body cameras, and other embedded applications beyond camera phones and stand-alone digital cameras.
3) Nano Photonics is the study of the behaviour of light on the nanometre scale, and of the
interaction of nanometre-scale objects with light. Nano photonics can provide high bandwidth, high speed and ultra-small optoelectronic components. This technology has the potential to revolutionize telecommunications, computation and sensing. R&D has been continually going on to find light confining structures that can slow down, trap, enhance and manipulate light. Photonic structures can enhance light-matter interactions by a great intensity.
The applications of the devices that we design, fabricate and demonstrate are numerous: onchip light modulation (optically and electro-optically) and detection, networks on-chip, nonlinear phenomena, multi-material devices and platforms, microfluidics, basic physics, etc.
4) Plasmonics is the study of the interaction between electromagnetic field and free electrons in a metal. Free electrons in the metal can be excited by the
electric component of light to have collective oscillations. Plasmonics has the potential to bring optics down to the
same scale as electronics, with waveguides on the size order of
electronics metal lines. Scientists have high hopes that
the emerging field of plasmonics can improve technologies such as
photovoltaics, LEDs, and other optoelectronics. It’s a natural
fit: Plasmonics exploits the oscillations in the density of electrons
that are generated when photons hit a metal surface.
The scientists have been working on incorporating plasmonic nanostructures into different
optoelectronics such as solar cells, light-emitting diode, and multicolour photodetector
which will a major breakthrough in optoelectronics.
5) Fibre-Optic Laser Transmitters will continue to be the fastest growing optoelectronics
product category as network operators struggle to keep up with huge increases in Internet
traffic, video streaming and downloads cloud-computing services, and the potential for billions of new connections in the Internet of Things. These are the preferred waveguides for
networks. They are the most cost-effective way to share information securely and reliably,
they’re insensitive to electrical interference and they have less weight and consume less
space than equivalent electrical links.
6) The development of Mid -Infrared Optics is based on the epitaxial growth of novel III-V
compound nanostructures and alloys. The mid-infrared spectral region is of enormous interest as the practical realisation of optoelectronic devices operating in the 2-10 µm wavelength
range offers potential applications in a wide variety of areas as molecules have resonance
modes in the mid-IR range.
They enable low cost, high volume production for the growing IR camera and sensor market,
higher quality and superior performance - Chalcogenide glasses have superior thermal performance compared to other infrared materials and can be used in environments up to 130°C
with much smaller focal shifts and consistent transmission .
