A New Optical Implementation of Reversible Fulladder Using Optoelectronics Devices

This study introduces a reversible optical fulladder. Also optical NOT and NOR gates are implemented through Electro-Absorption-Modulator / Photo Detector (EAM/PD) pairs, were utilized for fulfilling reversible R gate. Then, reversible fulladder was designed based on the proposed reversible optical R gate. The operation of the suggested fulladder was simulated using Optispice and it was found that the delay time in comparison with VLSI implemented circuit has remarkably improved.
