Design of low cross-talk and high-quality-factor 2-channel and 4-channel optical demultiplexers based on photonic crystal nano-ring resonator

In this paper, 2-channel and 4-channel optical demultiplexers have been designed based on photonic crystal nano-ring resonator. The structure of both demultiplexers is based on the use of a photonic crystal filter. The mean quality factor of 2828, mean transfer factor of 95%, mean cross-talk of − 25.07 dB, and an inter-channel distance of 7.4 nm are among the structural advantages of the 2-channel demultiplexer. The advantages of the 4-channel demultiplexer include the mean quality factor of 4525, mean channel power transfer factor of 95%, and maximum and minimum channel cross-talk of − 19.6 and − 40.4, respectively. Also, the inter-channel difference is 7.8 nm and mean channel width is 0.375 nm. Moreover, the simplicity of the structure and the small size are among the characteristics of these designs. The proposed 2-channel and 4-channel demultiplexers can be used in WDM systems, especially DWDM systems.
