Abstract:
The present invention provides a packaging structure of a laser and a grating coupler and its method, wherein: the packaging structure of a laser and a grating coupler comprises a laser unit, a collimating lens, an isolator and a reflecting prism that are provided on a silicon photonic chip; the silicon photonic chip comprises a first electrode, a first marker, a second marker, a grating coupler and a waveguide layer that are provided on a surface plane; the laser unit comprises a transition substrate and a laser; and the collimating lens comprises a first lens and a second lens, the first lens stands perpendicularly to the surface plane, and the second lens is provided on the surface plane by aligning with the second marker, so that the grating coupler is positioned in a central area of a principal axis of an optical path of the second lens, and the isolator is installed at a surface plane that is between the first lens and the second lens, so that a divergent light outputted by the laser is collimated by the first lens, passes through the isolator, becomes incident to the reflecting prism, is angularly deflected by the reflecting prism, and is converged by the second lens, wherein a convergence point is located at a surface of the grating coupler. Such a constitution solves the technical problem of accurate aligning and packaging, and simplies the manufacturing and improves the product yield.

Claim (Index 6):
The packaging method of a laser and a grating coupler according to  claim 5 , wherein: the first lens can be shifted to adjusted the position on the silicon photonic chip, so that the lights outputted by the laser collimated to become parallel light, and then the first lens and the silicon photonic chip are solidified by filling ultraviolet adhesive or thermosetting adhesive.
