A proper arrangement of photonic crystal waveguide and a point defect cavity gives an important application of photonic filter device in optical communications. We have studied a narrow band filter and a channel drop filter device using 2-D photonic crystal with square lattice structure. A narrow band filter is applied to select a narrow frequency band signal from incoming light, while a channel drop filter is used to drop a particular frequency signal from incoming light. Chalcogenide As{sub 2}S{sub 3} is compared with conventional Si material regarding applications as feasible material for optical devices.
