Abstract

In order to improve the transmission efficiency in eight-channel optical demultiplexers, we are going to use novel resonant cavities for performing the wavelength selecting function in photonic crystal demultiplexers. These resonant cavities will be created by removing one rod and reducing the radius of four rods. By incorporating eight cavities with different sizes for the reduced rods, we proposed a structure which is capable of separating eight optical channels with transmission efficiencies very close to 100%. The average channel spacing is about 3 nm. Crosstalk values vary between − 40 and − 16 dB.
