Abstract: Now a days almost all the peoples are using internet to do their task through wired or wireless network. Though Wi-Fi gives us speed up to 150 Mbps as per IEEE 802.11n which is not sufficient to service number of desired users. To solve this problem of Wi-Fi, the new concept of Li-Fi technology is introduced. Li-Fi stands for the light fidelity by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. Its the same idea behind infrared remote controls but far more powerful. can produce data rates faster than 10 Mbps. With this huge bandwidth preparation of Li-Fi, there is a propose in the insertion of optically interconnected networks with high-radix transparent optical switch fabrics. Silicon photonics is a particularly promising and applicable technology due to its small footprint, CMOS compatibility, high bandwidth density and the potential for nanosecond scale dynamic connectivity. In this study, shown the feasibility of building silicon photonic microring based switch fabrics for Li-Fi optical interconnection networks that can use a microring based switch fabric for WDM signals with this idea Li-Fi performance will improve by increasing switching speed over the backbone of the network. Also other researcher work on the applicability of silicon photonic microrings for data center switching and supercomputers that we need high speed switching.
