Abstract
By use of the Photonic Band Gap in the photonic crystal, the foundamental waveguide structures for the light wavelength range have been developed. Based on the fine structure of these ones, many functional devices have been proposed by the analytical or the numerical simulation methods and the experiments of the traial manufacture. In this paper, the treatment of chiral dielectric in the Condensed Node Spatial Network for the vector potential is explaiend, and we show the polarization plane rotation property in air-hole and pillar type photonic crystal waveguide structures with the chiral medium substrate. Then, we show the fundamental advantage of the air-hole type photonic crystal waveguide structure in application to a mode converter.
