Abstract

A four channel photonic crystals filter is designed using 2-D photonic crystals. First, General conditions for obtaining 100% drop efficiency are derived in a three-port channel drop filter. Based on this modeling, a photonic crystal-based four-channel drop filter is design. The performance of filter is simulation using 2D FDTD (finite difference time domain) method. The coupling efficiency of every channel is higher than 90% from seeing the simulation results. The frequency of the four-channel is from 1530nm to 1580nm when the lattice constant is 550nm, and the interval of every channel is less than 20nm. The interference of every channel is very small. The design method giving a good theory for design and made multi-channel photonic crystals filter.
