Implementation of All Optical 3 Bit Synchronous UP Counter using Micro Ring Resonator Structure

The Micro Ring Resonator is emerging as a leading technology in photonic computing and optical data processing applications. The old traditional circuit’s failure to withstand high frequency makes the MRR based all optical devices superior. The employment of an optically pumped signal enables us to circumvent conversion losses of an electrical signal. Thereby helping not just in reducing the complexity related to it but also lowering down the allied losses. This paper show case the notion related to all optical switching where MRR structure is used for the construction of all optical circuits. This work exhibit’s the implementation of an all-optical T flip-flop using MRR structure. This MRR based T flip-flop is further wielded in a cascaded network for the construction of a 3-bit UP counter. Designed UP Counter being Synchronous in creation does not require external clock pulse. Benefits of this synchronization is that all the individual output bits changes state identically in response to common clock signal. The Synchronous UP counter is capable of counting pulse from 000 to 111 (binary representation) in one cycle. The truth Table of the T flip-flop and the 3-bit synchronous UP counter is verified using MATLAB Simulation results. In this work we have tried to indulge all the mathematical modelling of the optical circuit constructed with the MRR structure. The design is unbound to complexity and can contribute in various field of optical domain.
