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.

“…All-optical switching is more advantageous than optoelectronics since it eliminates the need for converting between electric and optic signals. Researchers are currently developing various logic gates, combinational circuits, and sequential circuits employing all-optical switching [6] [7][8] [9]. All-optical switching requires low power and has a broad bandwidth, resulting in efficient data transport and fast signal processing.…”

This manuscript investigates the mathematical modeling of a silicon nitride-based all-optical BVF reversible gate, and reversible full adder modeled using an optical ring resonator (ORR). The design parameters of the proposed ORR are optimized to implement the desired mathematical model of reversible logic devices for all-optical computing. The transcendence of the proposed device is validated by the evaluated figure of merits like quality factor and contrast ratio. The CMOS compatibility nature of the silicon nitride-based structures also verifies the practical feasibility of the proposed device.

“…To build an optical device, different components such as optical gate, optical switch, memory etc are the requirement. In recent years, all optical logic gates and processors are designed using different switching mechanism such as, SOA, RSOA, TOAD, DCDSTOAD, ring resonator etc., with higher speed, smaller size and lower heat dissipation [2][3][4][5][6][7][8][9][10][11][12][13][14]. However, these devices have several disadvantages in terms of lower speed of operation, effect of spontaneous emission noise, higher foot print etc.…”

In this article we have presented all optical comparator using 2-D photonic crystal of silicon poles with dimensions 10a×12a. The structure of this device is very simple having small footprint of nearly 62 µm2. All-optical comparator has been validated by employing finite-difference-time-domain (FDTD) method. We have analyzed this device to calculate the ER, CR and Q value and verified the output by optical field distribution and amplitude with frequency. The performance of the all optical comparator has been investigated by calculating the variation of ER,CR, Q and transmission ratio with wavelength of the input signal and rod radius.
