Review of Optical Link Technology in Silicon Photonic Circuits

Silicon photonics is the new advancement in the field of highly integrated devices on a single semiconductor substrate. The wide availability of fabrication facilities, high-density integration of photonic devices and the high probability of monolithic integration with electronic circuits offer the prospect for future reliable, low cost and energy-efficient. Silicon integrated chips have the capability to generate, modulate and analyse the light signals. Hence the have a varied application in computing, communications and sensing and optical interconnects. The application of photonics in optical interconnects is discussed in this paper. Here in we review recent progress in the engineering of new devices and important elements in silicon photonics, including low-loss waveguides, micro-ring resonators, modulators, photodetectors, transmitter and receiver architecture. We summarise the various types of optical ring resonators and coupling methods, in the paper. An attempt is also made to demonstrate the simulation of the single and double ring waveguides in LUMERICAL software.
