An All-optical New Universal Gate Using Mach-Zehnder Interferometer

From the seventies of the last century the all-optical universal logic gate has formed as an unconventional form of computing. It is very new relatively in the area of extensive applications in low power CMOS, quantum computing, DNA computing, digital signal processing ( DSP), nanotechnology, communication, computer graphics, etc. Here we present and configure a new universal gate ( AG gate) in all-optical domain and also in this paper we have explained their principle of operations and used a theoretical model to fulfil this task, finally supporting through numerical simulations. In the field of ultrafast all-optical signal processing Mach-Zehnder interferometer ( MZI), semiconductor optical amplifier ( SOA)-based, has an important function. The different logical ( realization of Boolean function) operations can be executed by designed circuits with AG gate in the domain of reversible logic-based information processing.
