Photonic crystal based flat-top filter for CWDM channel compatible with ITU-T recommendation G.694.2

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-x Ge x alloy, with Silicon Nitride (Si 3 N 4 ) has been effectively found compatible as pri...

Description
Summary: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-x Ge x alloy, with Silicon Nitride (Si 3 N 4 ) has been effectively found compatible as primitive layers of unit cells instead of Si/SiO 2 pair. Finally CST MW simulated results have been presented, for comparative purpose, to demonstrate the amenities of Si 1-x Ge x /Si 3 N 4 pair, over Si/SiO 2 pair, as basis of the photonic crystal.
