Silicon photonic devices comprise of the optical systems that use silicon as the optical medium. Since, silicon is used as a substrate for most ICs, it is easily possible to manufacture hybrid devices in which electronic as well as the optic components are incorporated on a single microchip. Thus, owing to their combined electronic properties, the potential of electro-optic and optoelectronic interactions of electrons and photons is added. This results in electrical excitation and manipulation of light as well as optical conversion to electrical signals. Therefore, they are increasingly used in data transfer between microchips, through optical rays. Also, they are capable of carrying large amount of data in less time as compared to the electrical conductors. Cloud computing performance needs for data center, rapidly growing internet traffic, and reducing bandwidth are some of the major factors driving the growth of the silicon photonic market. The silicon photonic technology uses lase...
