Electro-Optic Activity of a Non-Ideal One-Dimensional Photonic Structure in the Frequency Vicinity of Excitonic Transition

Abstract

The paper is devoted to electro-gyration phenomenon in a non-ideal one-dimensional photonic crystal. One of the sublattices of the considered structure includes randomly distributed foreign layers with embedded point imperfections (vacancies). Electro-gyration effect arises due to the onset of optical activity of defect layers under the action of a constant electric field. We study the dependence of the specific polarization rotation angle of light on concentrations of layer wise and point defects as well as on the light frequency and lattice parameters.
