Abstract
A new method to optimize transmission of photonic crystal filter composed of coupled cavities is proposed. This method can improve transmission without changing 3 dB bandwidth and it is achieved by shifting the defect rods in two cavities centripetally to shorten the distance between energy distribution centers within two cavities. Finally, an ultra compact four-channel demultiplexer is demonstrated by using this optimization method, and this device satisfies the coarse wavelength division multiplexing standard of ITU-T G.694.2 with transmission 99% for each channel.
