Proposed all-optical read-only memory element employing Si3N4 based optical microring resonator

Abstract

All-optical processors and logic circuits are already doing wonders in the current research technologies. In connection to high-speed processors, this manuscript demonstrates a novel technique to implement an all-optical read-only memory element using an optical microring resonator. In the given article the authors have analysed the numerical modelling of Si3N4 based optical microring resonator (MRR). This silicon nitride-based MRR is modulated using an optical pumping signal which ultimately helps to achieve the optical switching through the constructed device using its nonlinear properties. The theoretical studies of the devices have been proved using simulation analysis. The obtained figures of merit like on-off ratio, extinction ratio, quality factor and finesse are very promising thus proves the practical feasibility of the proposed structure
