Design and simulation of a novel structure for WDM communication demultiplexerhas been done. In this work, by using X-shaped ring resonators in a 2-D photonic crystal structure, the desired wavelengths for communication systems could be selected and simulations show that its important characteristics such as crosstalk, channel spacing and quality factor are appropriate for optical communication applications. Scattering rods that used in the rings play very important role in the central wavelength of the output channels in proposed demultiplexer. Minimum crosstalk value is -16 dB and maximum of it is -11 dB. In addition, the efficiency of the designed demultiplexer is enough for communication systems..
