英文摘要A grating coupler comprising an optical waveguide (12) and a grating (13) formed on the optical waveguide in which light is propagated for optically coupled light rays inside and outside of the optical waveguide, wherein the coupling coefficient of the grating coupler is gradually changed in the direction of propagation of guided light in the optical waveguide, whereby the intensity distribution of light rays inside or outside of the optical waveguide agrees with the coupling efficiency distribution of the grating coupler, so the coupling efficiency of the grating coupler can be improved.
