A coupling structure includes a single mode active device and a planar optical waveguide. Specifically, the planar optical waveguide includes a silica waveguide for transmitting an optical signal, where the silica waveguide includes a coupling section and a conduction section; the coupling section is of a regular trapezoidal structure or an inverted trapezoidal structure, where a surface of the coupling section coupled to the single mode active device is a trapezoid top, and a surface of the coupling section connected with the conduction section is a trapezoid bottom; and a coupling gap is preset between the single mode active device and the planar optical waveguide.
