Introduction
Silicon photonics is an evolving technology in which data is transferred among computer chips by optical rays. Optical rays can carry far more data in less time than electrical conductors. Its overarching goal is to develop high volume, bolt-and-go optical components using silicon. While silicon is opaque in the visible spectrum, it is transparent at the infrared wavelengths used in optical transmission, hence it can guide light.
Features of - Photonics
phase insensitive.
frequency conversion WDM meets perfectly the requirements of ultra fast all data optical data.
processing and regeneration.
alternative or supplement to semiconductor-based photonics.
Silicon Material
Amorphous silicon
Porous silicon
Black silicon
Light propagation through silicon crystal
Silicon Light Source
The work towards a silicon-based emitter is ongoing but still far from nature. Until an efficient, reliable silicon based light source is available, a photonic integrated system will need to use a conventional III-V material light emitter.
