Design of All-Optical Universal Gates Using Plasmonics Mach-Zehnder Interferometer for WDM Applications

摘要

All optical integrated circuits have great application in high-speed computing and information processing to overcome the limitation of conventional electronics. In this work, a novel design of all optical universal gates using optical Kerr-effect and optical bistability of a plasmonics-based Mach-Zehnder interferometer (MZI) has been proposed. A MZI is capable for switching of light which depends on the intensities of optical input signal. The study of device is carried out using finite-difference-time-domain (FDTD) method and verified using MATLAB simulation.
