The Mach-Zehnder interferometer (MZI) is a common structure for integrated all-optical switches. We proposed and designed an all-optical 2x2 switch that is based on the MZI, multimode interference, and a nonlinear two-mode interference waveguide. The beam propagation method is used to simulate and analyze the device. The results show that the switching action is done properly.
