Abstract :
In this paper a photonic crystal based band pass filter has been designed to meet ITU-T recommendation G.694.2 for CWDM system, by varying the constitutive materials of the unit cell. The amalgamation of Si1-xGex alloy, with Silicon Nitride (Si3N4) has been effectively found compatible as primitive layers of unit cells instead of Si/SiO2 pair. Finally CST MW simulated results have been presented, for comparative purpose, to demonstrate the amenities of Si1-xGex/Si3N4 pair, over Si/SiO2 pair, as basis of the photonic crystal.
