“…OMRR based optical switch is a suitable choice to develop various sequential and combinational circuits. Available literature provides different techniques to implement all-optical J-K flip flop [14,15], D flip flop [16][17][18][19][20][21][22] and S-R flip-flop with ring resonators [23]. In the present work, an attempt is made to the implementation of D-flip flop and two-bit all-optical down-counter using GaAs-AlGaAs based OMRR.…”

Optical switches play a key role in the field of high-speed optical fiber communication and signal processing. Present work shows the design and implementation of D-flip flop and a two-bit optical counter using optical micro ring resonator (OMRR). The design of the proposed model is developed by considering nonlinear material-based resonators. Here, three OMRR based optical switches are used to design the D-flip flop circuit thereafter two-bit optical counter is implemented using the modeled D-flip flop. The mathematical model of the D-flip flop circuit is provided in the Z-domain by unit delay signal processing approach. The effectiveness of the proposed D flip flop and two-bit down counter circuit is described in the present work. The accuracy and feasibility of the circuits are determined by estimating various performance parameters during simulation.
