| Description | Multimode interference in optical waveguide is attractive for all optical switching. In this paper, a novel 3×3 all-optical switch based on 3×3 multimode interference (MMI) structures is proposed. Nonlinear directional couplers in two arms of the structure are used as phase shifters. In this study, we use chalcogenide glass on silica for designing the device structure. The switching states of the device can be controlled by adjusting the optical control signals at the phase shifters. The transfer matrix method and beam propagation method (BPM) are used for designing and optimizing the device structure. |
