Abstract
A coupler and a waveguide chip including the coupler are provided. The coupler connects a first optical waveguide to a second optical waveguide and includes an entity region and a first waveguide grating. A first end of the entity region is coupled to the first optical waveguide. A second end of the entity region is coupled to a second end of the first waveguide grating. A first end of the first waveguide grating is coupled to the second optical waveguide. Size of the first end of the entity region matches size of an end plane of the first optical waveguide, size of an end plane of the second end of the entity region matches size of an end plane of the second end of the first waveguide grating, and size of the first end of the first waveguide grating matches size of an end plane of the second waveguide.
