Polarization properties of defect mode in one-dimensional magnetic photonic crystal

Using 4 × 4 transfer matrix method, we investigate the polarization properties of defect mode in magnetic photonic crystal consisting of gyrotropic material. It is found that the position of the defect mode significant depend on the polarization of the incident light and the intensity of the applied magnetic field. As the intensity of the magnetic field increases, defect modes move toward lower frequency for right-circularly polarized light or higher frequency for left-circularly polarized light. Furthermore, we also find that position of the defect modes critically depend on the thickness of magnetized medium.
