Abstract: The present application provides an optoelectronic chip integrated system and manufacturing method thereof. The optoelectronic chip integrated system includes a laser, a free-from surface coupler, and a chip. The laser is configured to emit a light beam. The free-form surface coupler is on a light path of the light beam emitted from the laser, and is configured to receive, reflect and shape the light beam. The chip is connected with the laser, and includes a waveguide structure, where the waveguide structure is connected with the free-form surface coupler, and is configured to receive the reflected and shaped light beam.

Abstract: Reflecting light beams off of microscale three-dimensional (3D) freeform surfaces can yield highly efficient coupling into and out of optical waveguides, optical fibers, and photonic chips. The structure of the 3D freeform reflective surface determines the shape of the reflected beam. This allows freeform reflectors to control the mode profile, rotation angle, and divergence angle of light beams. Control of beam shape enables mode matching between source output mode and target input mode, which results in low-loss optical coupling. An inventive freeform reflective surface can direct light beams in plane or out of plane via specular reflection or total internal reflection. A photonic integrated circuit with this type of freeform optical coupler can operate with a bandwidth range of at least 400 nm, potentially encompassing all visible or telecommunications wavelengths, and can be volume manufactured in photonic chips.
