Abstract

An optical filter based on photonic crystal structure has been proposed in this paper. For designing the proposed filter we introduced an L3 resonant cavity between the input and output waveguides. We study the impact of different parameters on the filtering behavior of the structure using plane wave expansion and finite difference time domain methods. The initial form of this filter is capable of selecting the optical waves at =1555 nm and the transmission efficiency of the filter is obtained about 100%..
