Abstract
The invention relates to a photonic crystal magneto-optical circulator, which comprises first dielectric material columns in an air background, wherein the first dielectric material columns are arranged in the form of two-dimensional square lattice. The photonic crystal magneto-optical circulator also comprises a “T-shaped” or a “cross-shaped” photonic crystal waveguide, a second dielectric material column, four same magneto-optical material columns and at least three same third dielectric material columns, wherein the “T-shaped” or a “cross-shaped” photonic crystal waveguide comprises a horizontal photonic crystal waveguide and a vertical photonic crystal waveguide which are intercrossed; the second dielectric material column is arranged at a cross-connected position of the horizontal photonic crystal waveguide and the vertical photonic crystal waveguide and has the function of light guiding; the four same magneto-optical material columns are uniformly arranged on the periphery of the second dielectric material column; and at least three same third dielectric material columns.
