Abstract

An enhancement of Faraday rotation effect can be fulfilled in one-dimensional (1-D) magneto-photonic crystals (MPCs). Numerical calculations imply that the simple multilayer films with only two magnetic layers can meet the need of optical isolator (transmission ratio T>95% and Faraday rotation angel thetas_F = 45⁰). The structure is (N₂/N₁)³/M/(N₁/N₂)³/N₁/(N₂/N₁)³/M/(N₁/N₂)³, where N₁, N₂, M are SiO₂, GaAs, Bi:YIG, respectively. In this short paper we will analyze the error in thickness and refractive index of each layer.
