Abstract
The design of a new multifunctional integrated optical device capable of operating simultaneously as an optical switch and optical isolator is presented. The device consists of a multilayer directional coupler employing one nonlinear and one magneto-optic layer, with all other layers being linear and isotropic. Therefore, only phase matching conditions are required for the device operation irrespective of the propagation directions and operation regime (linear/nonlinear). The structure is optimized via a genetic algorithm and tested with a numerical formalism based on the wide-angle finite-difference beam propagation method. The results clearly demonstrate the ability of performing two distinct functions on the same device.
