We design and simulate an efficient wavelength division demultiplexer (WDDM) based on photonic crystal without using either specific materials or complexities in the fabrication process. The photonic crystal consists of a square lattice of Chalcogenide glass with embedded in air in two dimensions. The structure involves three cavities around the boundary of the waveguide with specified distance from each other for wavelength selection. For obtaining resonant frequencies of the cavities, two dimensional Finite-Difference-Time-Domain (FDTD) simulation is used. Through simulations, characteristic resonant wavelengths of the cavities are obtained in terms of the size of the coupling rods and the inner rod of the cavity. To show the design flexibility of the proposed structure, a WDDM is designed to divide a common input containing wavelengths and into three distinct ports with a high efficiency..
