Abstract: A packaging structure and a packaging method of edge couplers and a fiber array are provided. The packaging structure includes a silicon substrate, an edge coupler, and a fiber array. Multiple edge couplers are arranged in a main body portion of the silicon substrate, and an end of the edge coupler extends to a step groove of the silicon substrate. At least a part of the cover of the fiber array is accommodated in the step groove. Multiple fibers in the fiber array correspondingly pass through multiple lead channels of the cover and are then coupled with the edge couplers in the step groove. The edge couplers butt the fibers in the fiber array. The cover is moved until a part of the cover is accommodated in the step groove, so that the fibers can be aligned with the edge couplers in the step groove.

Abstract: This application discloses a frequency modulated continuous wave LiDAR and an autonomous driving device. The LiDAR includes a light source module, a silicon photonic chip and a refraction module, and the silicon photonic chip includes a light splitting module, a coupling module and multiple transceiving units. The light splitting module receives a laser beam coupled into the silicon photonic chip, divides the laser beam into multiple beams of detection light, and transmits the multiple beams of detection light to corresponding multiple transceiving units, and the transceiving units emit the received detection light outward. The refraction module is configured to refract the detection light emitted by the multiple transceiving units to emit multiple beams of detection light in a staggered manner in a second direction, where the second direction is a direction perpendicular to the terminal surface of the transceiving unit.
