We propose an ultra compact structure for DWDM systems using resonance cavity in Photonic Crystal structure. This is for the first time that a PC-based demultiplexer has been achieved with 0.8nm channel spacing, -18.77dB and 4170 average crosstalk and quality factor, respectively without using particular materials or complexities in fabrication.
