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.

Device and method are provided to align and bond a lens array to a PD array with high precision, which can implement aligning and bonding of the lens array automatically. A telescopic rod of the stepping actuator is adjusted until photosensitive areas of the PD array form a clear image on the image acquisition CCD through the lens array, an adjusted distance h1 of the telescopic rod is recorded, and a position coordinate (xn, yn) of center of each circular photosensitive area in the image may be obtained, and a slope k1 of a line connecting the centers of the photosensitive areas is calculated. The telescopic rod is adjusted again, and a slope k2 of a line connecting the centers of the apertures of the lens array is calculated. Based on calculated values &#x394;xn, &#x394;yn, arctan(k1)&#x2212;arctan(k2), the high-resolution adjustment stage is adjusted to adjust position of the lens array.
