Optical component
First Claim
1. An optical component optically coupled to an optical fiber, the optical component comprising:
- a substrate, comprising an accommodating cavity, a plurality of openings, a waveguide, an optical coupler and a plurality of pads, wherein the waveguide and the optical coupler are distributed outside the accommodating cavity, the plurality of openings are distributed at a bottom surface of the accommodating cavity, the plurality of pads are located at bottoms of the plurality of openings, and the optical coupler is optically coupled to an end of the waveguide and comprises a light-incident surface; and
an edge-emitting laser, embedded in the accommodating cavity and comprising a light-emitting layer and a plurality of bumps located in the plurality of openings and electrically connected to the plurality of pads, wherein a ratio of a level height difference between the light-emitting layer and the optical coupler to a thickness of the optical coupler ranges from 0 to 0.5, and a light emitted from the light-emitting layer enters the optical coupler through the light-incident surface and is transmitted to the optical fiber through the waveguide.

Abstract
An optical component optically coupled to an optical fiber includes a substrate and an edge-emitting laser. The substrate includes an accommodating cavity, a plurality of openings, a waveguide, an optical coupler and a plurality of pads. The waveguide and the optical coupler are distributed outside the accommodating cavity. The openings are distributed at the bottom surface of the accommodating cavity and the pads are located at the bottom of the openings. The optical coupler is optically coupled to an end of the waveguide and includes a light-incident surface. The edge-emitting laser is embedded in the accommodating cavity and includes a light-emitting layer and a plurality of bumps located in the openings and electrically connected to the pads. The ratio of the level height difference between the light-emitting layer and the optical coupler to the thickness of the optical coupler ranges from 0 to 0.5.
