Abstract

This article present a unique approach for the implementation of all-optical magnitude comparators and J-K flip-flop. In this paper we have presented a numerical analysis of Si3N4 based optical microring resonator. The Si3N4 based microring resonator is modulated using optical pump signal. In this article we have utilised the nonlinear properties of silicon nitride to obtain the switching of signal and the theoretical study is proved using simulation results. We have also obtained the various figures of merit like on-off ratio, extinction ratio, quality factor and finesse which proves the practical feasibility of the proposed structure.

Keywords
