A nano-ring resonator based on 2-D hexagonal-lattice photonic crystals

Abstract

We proposed a novel channel drop filter based on two dimensional (2-D) silicon hexagonal-lattice photonic crystals (PCs). The PC filters consist of hexagonal silicon nano-ring resonator and two terminal waveguides by removing arrays of air cylinders of the same trace arranged in the hexagonal lattice of a silicon thin plate. The effects of the coupling distance between resonator and waveguides are studied. By integrating dual nano-ring resonators to form the filter, we demonstrated a two-port channel drop function. ©2009 IEEE.
