Problems solved by technology

[0002] Most of the traditional laser chips are edge-divergent chips. The waveguide is on the plane and emits light from the side. When packaging, the chip needs to be vertically attached to the carrier, and the angle of light output is relatively large, which affects the coupling efficiency of light.

Abstract

The invention relates to a small-emission-angle front light emitting laser. The small-emission-angle front-light-emitting laser comprises a carrier, an optical waveguide of the laser is attached to the surface of the carrier, the side face of the optical waveguide emits light, and the light emitting direction of the optical waveguide is parallel to the carrier; the surface of the carrier is further provided with an etching reflector, the etching reflector is arranged in the light emitting direction of the optical waveguide, the face, right opposite to the light emitting side face of the optical waveguide, of the etching reflector is a 35-55-degree inclined face, the inclined face is provided with a pit, the surface of the pit is plated with a reflection medium, light emitted by the optical waveguide is emitted to the pit to generate reflection of 80-100 degrees, and the pit reflects the light emitted by the optical waveguide at 80-100 degrees and simultaneously has the effect of focusing the light or the effect of reducing the divergence angle. According to the small-emission-angle front-light-emitting laser, light is focused through reflection of the inclined plane and the pit, the divergence angle can be effectively reduced, and the coupling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a laser that emits light from the front with a small emission angle. Background technique [0002] Most of the traditional laser chips are edge-divergent chips, the waveguide is on the plane, and the side emits light. When packaging, the chip needs to be vertically attached to the carrier, and the angle of light output is relatively large, which affects the coupling efficiency of light. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a laser that emits light from the front with a small emission angle and effectively improves the optical coupling efficiency. [0004] For realizing the purpose of the present invention, the present invention adopts following technical scheme: [0005] A laser with a small emission angle that emits light from the front, including a carrier, the surface of the carrier is bonded with an opt...
