Paper Abstract

A new channel drop filters (CDFs) configuration based on a single line-defect resonator (LDR) is presented. The proposed structure is composed of a bus waveguide, a LDR and a u-shaped output waveguide. The bandgap structure and filter characteristics of the filter are investigated by using the plane wave expansion (PWE) method and finite difference time domain (FDTD) method in a square lattice dielectric rod photonic crystal structure respectively. Though this novel resonator, the two wavelengths at 1531nm and 1551nm are dropped from the two ports of the u-shaped output waveguide with high dropping efficiency. This is very well meeting the requirement of ITU-T G.694.2 standard. The proposed CDF can play important role in optical communication networks and photonic integrated circuits.
