Abstract

We present design and modeling of photonic crystal (PC) hybrid waveguides with quasi-flat transmission band. The finite-difference time-domain (FDTD) and coupled-mode theory (CMT) methods are used to simulate the PC hybrid waveguide of square lattice. The bandwidth of the hybrid waveguide is investigated for different radius of the coupled cavities. The transmission of a 200-fs pulse at 1550 nm is simulated by using the FDTD method, and the transmitted pulse shows very little distortion.
