Abstract:
1. A photonic crystal magneto-optical circulator comprising first dielectric material columns in an air background, wherein, said first dielectric material Pateros amounts but in said photonic crystal are arranged in the form of two-dimensional square lattices; each said first dielectric material column occupies one of said square lattices; the center-to-center distance between any two adjacent horizontal or vertical said first dielectric material columns is one lattice constant; and the photonic crystal magneto-optical circulator also comprising a “T-shaped” or a “cross-shaped” photonic crystal waveguide comprising a horizontal photonic crystal waveguide and a vertical photonic crystal waveguide which are mutually cross-connected; a second dielectric material column arranged at a cross-connected position of said horizontal photonic crystal waveguide and said vertical photonic crystal waveguide and having the function of light guiding; four same magneto-optical material columns uniformly arranged on the periphery of said second dielectric material column; and at least three same third dielectric material columns respectively arranged on the outsides of three said magneto-optical material columns.
