Abstract: Logical reversibility refers to a one-to-one mapping, allowing the inputs to be traced by examining the outputs. This concept is becoming increasingly important in fields like nanotechnology, quantum dot cellular automata, and quantum technology, as it reduces heat dissipation while effectively preserving data. With an emphasis on utilizing the fewest possible Electro-optic Mach-Zehnder Interferometers (EO-MZI) i.e., minimal optical cost, this study investigates the Peres Gate (PG) implementation based on EO-MZI.Furthermore, the concept of reversibility allows the circuit to preserve bits, thereby supporting Launder's limit. OptiBPM tool is used to investigate the design, and MATLAB is used to validate its mathematical power equation. The work also explores full adder (FA) utilizing the PG as the core logic element. This leverages the unique properties of PG to configure EO-MZI count optimized reversible full adder. Along with design, simulation, and analysis of the PG-based FA, this work also explores the system-level validation to ensure the correct operation of the FA in terms of wavelength () and horizontal diffusion constant ().
