A wavelength demultiplexer based on two dimensional photonic crystal waveguides is proposed. By using the finite differ-ence time domain (FDTD) method and plane wave extension (PWE) method,the transmission spectra and the distributions of mode field are obtained,and the wavelength demultiplexer has been synthesized. The characteristics of the device are obtained.
