All-Optical Implementation of Arithmetic Operation Scheme using Optical Nonlinear Material Based Switching Technique

Abstract

Nonlinear material based all‐optical switching mechanism is utilized here to develop the all‐optical arithmetic operation scheme. Analog optical signals are converted to the corresponding digital signals by optical tree architectures. First a four bit arithmetic unit has been accessed which is elevated to a higher bit arithmetic unit in course. These circuits can execute innumerable arithmetic operations and remarkably, as they are all‐optical and fully parallel in nature. These all‐optical arithmetic units can gear up to the highest capability of optical performance in high‐speed all‐ optical computers.
