The adder is a highly fundamental part of the central processing unit. The carry lookahead adder (CLA) has become the fastest adder used in digital circuits. For high-speed operations, optical computing has become an essential research field. In this manuscript, a microring resonator (MRR)-based all-optical (AO) CLA is proposed and analyzed. The MRR-based AO design is capable of getting a higher operational speed to fulfill the demands of end users. The Z domain's mathematical model of the CLA is developed using the unit delay signal processing method. The numerical simulations validate the proposed circuit's operational speed of close to 260 Gbps. The parameters for this design are chosen optimally to enable it to be effectively implemented for optical computations.

Silicon micro-ring resonator-based generation of all-optical (2 × 2) Walsh-Hadamard code is proposed. The energy-efficient, ultra-high-speed, and compact nature of micro-ring resonator-based devices is essential for optical computing. Both MATLAB and the Ansys Lumerical finite difference time domain (FDTD) approach are used to implement the generation of all-optical (2 × 2) Walsh-Hadamard code. The proposed design is simulated at about 260 Gbps. In the recommended circuit, the needed pump power for switching is merely 0.84 mW, which is extremely little in contrast. The "figure of merits" of the proposed design is evaluated through numerical simulation. The obtained contrast ratio and extinction ratio are considerably greater at 25.24 and 14.63 dB, respectively. On the other hand, the achieved amplitude modulation of 0.13 dB is extremely low. The on-off ratio for a single micro-ring resonator is 36.9 dB.

“…In all optical logic processing still there are many unsolved challenges [2]. All optical logic implementations includes simple logic operations like OR, NOT, XOR etc [3], half adder [4], full adder [5], comparator [6], flip-flops [7], parity generator-checker [8], code converters [9], programmable logic array [10], canonical logic unit(CLU) [2] etc. Among these CLU and PLA together is very effective for implementation of different complex logic processors for high speed optical processing.…”

This paper describes design and analysis of all-optical majority gate. Modifications of the design in comparison to conventional design using three AND gates have improved the performance as far as optical majority gate is concerned. The control power the TOAD is optimized by calculating different performance indicating parameters and noise characteristics is also investigated. Optimized values of extinction ratio (~16 dB), amplitude modulation (~0.1dB), quality factor (~20 dB), contrast ratio (~20 dB), and relative eye opening (>97%) show overall efficient performance of the device. The operating speed of the device is 1Tb/s.
