Abstract

This work presents all optical reversible implementation of sequential counters using semiconductor optical amplifier (SOA) based MachZehnder interferometer (MZI) switches. With the advancements in semiconductor technology, there has been an increased emphasis in low-power design techniques over the last few decades. Reversible computing has been proposed by several researchers as a possible alternative to address the energy dissipation problem. Several implementation alternatives for reversible logic circuits have also been explored in recent years, like adiabatic logic, nuclear magnetic resonance, optical computing, etc. Recently researchers have proposed implementations of various reversible logic circuits in the all-optical computing domain. Most of these works are based on semiconductor optical amplifier (SOA) based MachZehnder interferometer (MZI), which provides desirable features like low power, fast switching and ease of fabrication. All the designs are implemented using minimum number of MZI switches and garbage outputs. This design ensures improved optical costs in reversible realization of all the counter circuits. The theoretical model is simulated to verify the functionality of the circuits. Design complexity of all the proposed memory elements has
