Analysis of Polarization Plane Rotation Characteristic in 2D Photonic Crystal Waveguide with Chiral Medium by Condensed Node Spatial Network

摘要

Using the photonic band gap in photonic crystals, the fundamental waveguide structures for the light wavelength range have been developed. Based on the fine structure of these many functional devices have been proposed by analytical or numerical simulation methods and the experiments of trial manufacture. In this paper, the treatment of chiral dielectric in the Condensed Node Spatial Network for the vector potential is explained, 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.
