Faraday rotation in one-dimensional magnetic photonic crystals in electric field

In the last few years, magnetic photonic crystals (MPCs) or magnetic photonic bandgap materials, are the objects of intensive investigations because of promising application in photonics [1]. A large enhancement of the Faraday rotation (FR) in one-dimensional (1D) MPC was reported [2,3]. In this report, the influence of external electric field on the FR in 1D MPC with magnetic and non-magnetic defect layers is theoretically studied. For the theoretical description of FR we introduce electrical polarization, which depends on magnetization and external electric field. Numerical calculations of the dependence of FR on the strength and the direction of electric field is done for the 1D MPC based on yttrium-iron garnet. [1] I. L. Lyubchanskii, N. N. Dadoenkova, M. I.
