| titleOfInvention | Silicon-based artificial microstructure super-surface waveguide coupler |
| abstract | The utility model discloses a silicon-based artificial microstructure super-surface waveguide coupler, which comprises a substrate, a silicon dioxide layer and a top layer, wherein the top layer comprises a left artificial microstructure super-surface and a right waveguide, and the artificial microstructure super-surface is arranged on one side of an optical waveguide port; incident light is vertically irradiated downwards, phase delay is obtained on the super surface of the artificial microstructure, additional surface transverse wave vectors are introduced, the surface transverse wave vectors are equal to effective transverse wave vectors of a waveguide working mode, the wave vector matching condition of waveguide coupling is met, and therefore the vertically incident light is coupled into the waveguide for unidirectional propagation. The utility model discloses a super surface of silica-based artificial microstructure is designed, makes the linear polarization light of vertical incidence couple into the optical waveguide with high efficiency to unidirectional propagation in the optical waveguide, has restrained the process that the light in the optical waveguide couples into the free space backward, has further improved the coupling efficiency of space light to the optical waveguide; can be compatible with the existing CMOS processing technology, greatly reduces the cost and has wide market prospect. |
