Design of all-optical new gate using Mach-Zehnder interferometer

Reversible logic is an emerging research area and getting remarkable interest over the past few years. Reversible computation plays an important role in the synthesis of circuits having application in quantum computing, low power CMOS design, bioinformatics and nanotechnology-based systems. Conventional logic circuits are not reversible. This paper proposes circuit realization of reversible logic gates, called New gate (NG) in all-optical domain. Semiconductor optical amplifier (SOA) based Mach-Zehnder interferometer (MZI) plays a significant role in this field of ultra fast all-optical signal processing and is used here.
