Abstract

An all-optical switch based on nonlinear ring resonator in a photonic crystal is proposed in this paper. The size of the structure proposed is 18a 18a, where a=0.609 m is the lattice constant of the device. Graphene is used as the nonlinear material and wave absorbing material. The optical switch has been investigated by finite difference-time domain (FDTD). In order to reduce the scattering and improve the coupling efficiency, four scattering rods and six coupling rods are set as composite layers with graphene material inside the ring resonator, respectively. The all-optical switch shows excellent performance for having short switching time and desirable contrast ratio, which are 10.43 ps and 36.8 dB, respectively.
