Abstract :
In this article decreasing of crosstalk phenomenon optic two-channel demultiplexer to use in DWDM communicational systems with 2D photonic crystal structure has been suggested. In this research, designed two-channel demultiplexer resulted in decrease in crosstalk phenomenon to the average of -22.11 dB in photonic crystal two-channel demultiplexer according to ultra channel spacing with distance of 0.8 nm, ultra narrow bandwidth mean of 0.25 nm, and quality factor Q with ultra average amount of 6582. PWE calculation methods were used to obtain band structure and photonic band gap and FDTD numerical calculation method was used to obtain output spectrum of photonic crystal two-channel demultiplexer.
