Development of 3mm three-port Y-junction magnetic optica! circulator with two-dimensional magneto-photonic crystals

摘要

Two kinds of defect structures of two-dimensional (2D) magnetic-photonic crystal (MPCs) are envisaged to realize circulators in millimeter wave band. The band gaps of the two kinds of photonic crystals are calculated by the plane wave expansion method. The function of the circulator is simulated by finite element method. The calculated excellent external characteristics of the circulator show that MPCs is a promising way for generating an optical circulator.
