Theoretical Analysis of Chiral Mach-Zehnder Interferometer Based All-Optical Logic Gate

In this communication, we have theoretically analyzed the design of a Chiral Mach-Zehnder Interferometer (CMZI) based all-optical switch which can perform multifunctional logic operations.Here, we have placed a chiral material on the upper arm of the interferometer to produce the necessary polarization rotation and utilized the port-II which makes this design very efficient and promising.Numerical simulation using SCILAB has also been done to visualize the performance of the or logic.
