“…MRRs were preferred because the signal is carried in the form of photons only and it also has several advantages like miniaturized ring dimensions, lesser complex circuit, has narrow band, has high wavelength selectivity, and large free spectral range. Using MRRs a number of logic circuits like universal logic gates 1,[9][10][11] , combinational circuits like sequence generator 12 , multiplexer 13,14 , comparators 15 and sequential circuits like flip-flops 16 , counters 17,18 , reversible logic gates 19,20 , ALU reconfigurable logic operations 21 , etc. have been devised.…”

All-optical logic gates (AO-LGs) are the key elements that play a pivotal role in the development of future all-optical networks and all-optical computing. A complete overview of the seven all-optical logic gates (i.e., AND, OR, NOT, XOR, XNOR, NAND, and NOR) based on their design techniques and applications are covered, including the latest technologies, such as topological photonics and artificial intelligence-based designs techniques. In addition, we have further categorized the AO-LGs as reconfigurable gates, simultaneous gates, reversible gates, modulation-based gates, and data rate-based gates. The techniques to implement these different classes of gates are reviewed and their limitations are discussed. We also discuss in brief the various simulation tools used to design and analyze the AO-LGs. Finally, the most feasible techniques for constructing optical integrated circuits based on the existing fabrication technologies and available resources are explored, and future prospects are outlined.

“…A novel Micro-ring resonator-based switching activity can be effectively used for several optical logic computations and sensor design. Micro-ring resonator switching activity has been efficiently used for the implementation of the all-optical gray code converter [20], NAND logic gate, Half-adders [21], and some well-known combinational and sequential circuits [22]. The manuscript describes a theoretical mechanism to implement the all-optical 1 × 4 memory register using the ultra-fast switching activity of the micro-ring resonator (MRR) structure.…”

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 flipflops 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 × 4 memory registers.
