Abstract The construction of an all-optical frequency-encoded Toffoli gate employing a reflecting semiconductor optical amplifier (RSOA) is proposed in this article. By establishing fields such as quantum computing, optical quantum computing, quantum-dot cellular automata, and superconducting flux logic family, quantum gates have been proved to perform reliably in the present day. A nonzero-mass electron, on the other hand, moves far slower than a quantum particle with zero rest mass, such as a photon. Photons can also be utilized to store data while being sent. These photon qualities have motivated researchers to create quantum gates in the all-optical domain based on them. The RSOA-based implementation of the Toffoli gate gives a significant improvement in the case of high speed, low power, and fast switching time. MATLAB Simulink (R2018a) software is used to simulate the devised design. The theoretical prediction is satisfied by the simulation results.

Terahertz Optical Asymmetric Demultiplexer

The discovery of ultra-high-speed all-optical switches in the very recent past based on semiconductor optical amplifier (SOA) especially in the interferometric configuration is very pronouncing due to their features like high repetition rate, low power consumption, fast switching time, noise and jitter tolerance, being easily integrable and operationally versatile, thereby bringing a revolution in all-optical information processing systems. In this work, an all-optical computing tool namely SOA-based [Formula: see text] terahertz optical asymmetric demultiplexer (TOAD) is used because it can be employed to design more complex circuits and subsystems of enhanced combinational and sequential functionality. In this paper, (a) a switching network with its two switching actions and (b) an all-optical [Formula: see text] cross-bar network architecture, i.e., a multistage cube network for [Formula: see text] using TOAD-based [Formula: see text] optical cross-bar switch for discrete Fourier transform (DFT), are proposed. Numerical simulation of this work is done with OptiSystem v7.0 to evaluate the performance of the proposed circuit.

Abstract Implementation of switching activity in the all-optical domain is one of the most important aspects in the field of modern high-speed and secured communication technology. Micro-ring Resonator (MRR) based switching activity can be used to implement all-optical active low tri-state buffer logic and clocked D flip-flop. The paper describes the switching activity of micro-ring resonator structures and the switching activity is further used to implement the effective all-optical 4 - bit memory register using the appropriate arrangement of all-optical tri-state buffers and clocked D flip-flops with the functionality of RD and WR. The complete description of layouts and switching mechanisms of all-optical 4-bit memory registers have been explained and appropriate MATLAB simulation results are presented to observe the suitability of the proposed unit. The analysis shows that implementation of tri-state buffer logic and D flip-flop assisted 4-bit memory register in the all-optical domain includes the considerable advantages of optical communication e.g. immunity to electromagnetic interference, parallel computing, compactness, signal security, etc. The manuscript describes the detailed analysis of performance parameters e. g. extinction ratio, contrast ratio, amplitude modulation, on-off ratio, and switching speed of micro-ring resonator structures to achieve an efficient selection of device parameters and finally describes an efficient technique to implement all-optical MRR based 1 x 4 memory registers.
