Design of Mach-Zehnder modulator based optical reversible gate for high speed data transmission

Abstract

The limitation of conventional electronics is reduced by optical integrated circuits because of its high speed information and processing. Reversible logic gates are favorable in the processing of optical signals in optical domain. In all reversible gates inputs and outputs are correlated that is advantageous to collect the information from inputs and outputs. Reversible gates are useful in high speed data transmission with low power dissipation. Reversible gates are also used in quantum computing with low loss of information. In the current work, Reversible Feynman and Fredkin optical gates are designed using Mach Zehnder Modulator for high speed information processing. A Mach Zehnder Modulator has capability to switch the source light according biased electrical signal. The amount of biased electrical signal modulates the output. The reversible optical gates are used in optical switching, optical modulator and as protection switch. The proposed gates are explained with mathematical formulation and the truth table of the reversible gates is verified using Lumerical Interconnect tool.
