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 Si_1-xGe_x 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 Si_1-xGe_x/Si₃N₄ pair, over Si/SiO₂ pair, as basis of the photonic crystal.
