Design and simulation of an optical and and xor gate using micro ring resonator for photonic FPGA

Silicon photonics is an innovative technology that revolutionizes a number of domains such as data centres, high- performance computing, sensing and Field Programmable Gate Array (FPGA). The photonics based digital devices are utilized in low space and low power. Very Large Scale Integration (VLSI) designs pave ways for future photonics FPGA. Logic gates are the basic element for combinational and sequential models. The existing architecture used for the development of AND & XOR gates have more number of Micro Ring Resonators (MRRs) and consume a lot of space. In this paper design and simulation of XOR and AND logical devices using an optical MRR and Electro-optic effect has been explained. Electrical voltage source has been used as external input to achieve electro optic effect. A compact XOR and AND gate has been designed and can be easily fabricated using existing foundries. The designed and simulated XOR & AND logical devices occupies space of 500 μm² and consumes a power of 13.18 μW.
