Abstract
We propose a new all-optical switch by using the nonlinear asymmetric Mach-zehnder waveguide structure which is composed of a narrow nonlinear arm and a wide nonlinear arm. The light-induced index charges in the nonlinear asymmetric Mach-Zehnder waveguide structure break the symmetry of the structure and make the output beam swing in the uniform nonlinear medium. We investigate the characterization by using the beam propagation method. By properly launching the input power, the numerical results show that the proposed nonlinear asymmetric Mach-Zehnder waveguide structure could function as an all-optical switch.
