Abstract

Proposed manuscript includes the analysis and design of compact all-optical 1-bit binary full adder using microring resonator. Large-scale optical integrated circuits are being taken into account as a substitute for conventional CMOS technology in the field because to the growing demand for ultra-fast terahertz data transfer and processing. Furthermore, circuits that use less energy are becoming more and more important. The architecture is designed and analyzed at about 260 Gbps using MATLAB. The proposed design is simulated also in “Ansys Lumerical finite difference time domain (FDTD)” software. The footprint of the design in FTDD is only 34.1 x 32.2 μm2 . This proposed 1-bit full adder is particularly useful for digital signal processing because of its small architecture and faster response times. The evaluation and analysis of a few performance-indicating variables includes “extinction ratio”, “contrast ratio”, “amplitude modulation”, “on-off ratio”, “quality factor”, “photon cavity lifetime”, and “relative eye opening”. Optimized design parameters chosen to implement the design practically.
