摘要：
A novel simple control all-optical switching and routing mechanism using two nonlinear photonic crystal (PC) cavities and a T-branch waveguide has been presented. It has been shown that using a single control signal, the input power can be switched with a high-contrast ratio and routed to any of the two output ports. The performance of the proposed device has been investigated through the use of temporal coupled-mode theory (CMT) and two-dimensional (2D) nonlinear finite-difference time-domain (FDTD) simulations in PCs of square lattice.
