Simulation of a coupled system consisting of a defect bend and a cavity in photonic crystal

Abstract

A Photonic Crystal (PhC) of dielectric rods was considered for simulation of light propagation in the presence of defect. Two line defects were joined to create a bend defect. Cavities of different shapes were introduced near the bend at various positions. An electromagnetic beam of 1 μm was launch at the bend defect, and the coupling between the cavity and the bend was studied. © 2011 American Institute of Physics.
