Abstract :
In this research crosstalk phenomenon in DWDM two-channel communication demultiplexer was reduced by optimizing 2D photonic crystal network structure and using resonant cavity. Alongside with reduction in crosstalk phenomenon by mean of -19.74 dB, also the average bandwidth Δλ of 0.2 nm and mean transmission range of 93.47%, the average value of quality factor 7829.25 was reached. In these calculations using finite difference time domain method (FDTD), optimized structures of 2D DWDM two-channel communication demultiplexer photonic crystals to reduce crosstalk phenomenon was obtained.
