“…To develop all-optical flip-flops, various techniques have been proposed. For example, S-R flip-flops using dark-bright soliton 10 , all-optical D-flip-flop using single quantum dot semiconductor optical amplifier assisted Mach-Zehnder interferometer 11 , all-optical pseudorandom binary sequence generator based on D flip-flops using Terahertz Optical Asymmetric Demultiplexer (TOAD) 12 , polarization coded all-optical four-value R-S flip-flop using binary latch 13 . JK flip-flop, as the most versatile of the basic flip-flops, can be easily converted into SR, D, T flip-flops, and has become a focus of all-optical flip-flop field.…”

In this paper, we propose an all optical JK flip-flop system consisting of three vertical-cavity surface-emitting lasers with embedded saturable absorber (VCSEL-SAs) is proposed and numerically simulated. Also, the effects of injection intensity, delay and noise on the JK flip-flop are numerically analyzed. The results show that, based on the spiking dynamics of excited VCSEL-SA, the proposed alloptical JK flip-flop model can perform all the fundamental functions of conventional JK flip-flop under suitable bias current, injection intensity and perturbation delay between two trigger signals. Moreover, the noise has a little effect on the performance of JK flip-flop, but the proposed system has good robustness to the noise. The results provide a feasibility for the application of VCSEL-SA devices in the future ultrafast neuromorphic computing systems.

“…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.
