Abstract
In this paper, an all-optical switch based on photonic crystal directional coupler has been simulated and analyzed by the finite difference time domain (FDTD) method. An ultra small 3-channel wavelength division demultiplexer based on 2D photonic crystal was modified into all-optical switch suitable for integration. The output wavelengths of designed structure can be tuned for communication applications (around 1.5 µm, 1.4 µm, 1.3 µm) by locating suitable defect parameters in the corner of each resonance cavity and input waveguides. The bandwidth of each channel is about 1 nm.
