Photon Spectra of a Bragg Microresonator with Bigyrotropic Filling

Abstract

In this article, we have obtained the transmission spectra of a microresonator structure with Bragg mirrors, the working cavity of which is filled with a magnetically active finely layered ferrite-semiconductor structure with material parameters controlled by an external magnetic field. It is shown that a change in the external field and the size of the cavity (filling layer thickness) provokes a controlled rearrangement of the transmission spectrum of TM and TE waves. The polarization characteristics of the microcavity, their dependence on the external field, and the ratio of the thicknesses of the layers that make up the period of the ferrite-semiconductor structure are investigated.
