Implementation of some high speed combinational and sequential logic gates using micro-ring resonator

All optical logical operation is one of the most important aspects of modern research activity in the optical computing. The paper includes the detailed description of switching phenomena in the Micro-ring resonator (MRR). The Micro-ring resonator is very effective component for the implementation of various combinational and sequential logic devices, because of its small and compact size, immunity to electronic interference, low-attenuation, higher bandwidth and cheap computing. The literature includes the different combination of MRR in order to implement the combinational logic circuits (XOR/XNOR, AND, Full ADDER/SUBTRACTOR) and sequential logic circuits (D Flip-Flops). The results are verified by the MATLAB simulation.
