Polarization-independent directional anisotropic optical effect in magnetophotonic crystal

摘要

Polarization-independent directional anisotropic optical effect, a feature that has not been appreciated in the literature so far, in one dimensional magnetophotonic crystals consisting of ferromagnetic materials and anisotropic dielectric layers with misaligned in-plain anisotropy is investigated. We have known that such a configuration exhibits asymmetric spectrum at the certain frequency region [A. Figotin and I. Vitebskiy, Phys. Rev. B 67, 165210 (2003)]. In this paper, the existence of the directional anisotropic optical effect is examined according to 4 × 4 Muller matrix method based on the asymmetric properties of the system. Our results show that this effect can be realized in such magnetophotonic crystals without the existence of magnetization and polarization simultaneously. Furthermore, the order of magnitude of this unique electromagnetic effect can be up to 10~(-3).
