Paper Abstract

In this paper, a scheme for all-optical AND gate which exploits the cross-phase modulation (XPM) effect in an asymmetric semiconductor-optical-amplifier-assisted Mach-Zehnder Interferometer (SOA-MZI) has been proposed for the first time. No additional input beam such as a clock signal or continuous light is employed in the design, which is required in other AND operations. The scheme is validated and the system performance under various parameters is investigated through numerical simulations. This logic gate is helpful for future all-optical signal processing configurations.
