Abstract

The invention provides a laser base and a laser. The laser base comprises a substrate with two opposite surfaces, a baffle and a lens, wherein the baffle is arranged on the first surface, the substrate and the baffle are connected to form a containing cavity, and the containing cavity is used for containing a laser chip; a strip-shaped waveguide structure is arranged on the first surface, and a strip-shaped bulge is arranged on the second surface; a light outlet hole is formed in the end part of the strip-shaped bulge or in the position, corresponding to the strip-shaped waveguide structure, of the baffle; the lens is arranged at the light outlet hole; the strip-shaped waveguide structure is configured to guide light rays; the lens is configured to collimate light rays radiated by the laser chip or narrow the divergence angle of the light rays; or the lens is configured to focus the light incident from the outside. On one hand, coupling of the optical waveguide and the lens is achieved, on the other hand, collimation or divergence angle narrowing of radiation light of the laser emitting chip is achieved, and convergence of external incident light is achieved.

Description

technical field [0001] The invention relates to the technical field of laser packaging, in particular to a laser base and a laser. Background technique [0002] With the development of the optical communication industry, the commonly used transmitter optical sub-assembly (TOSA) and receiver optical sub-assembly (ROSA) have formed some relatively standardized packages, such as TO-CAN package and BOX hermetic package. The TO-CAN package is shaped like a cylindrical jar, consisting of a shell cap and a shell seat. The BOX hermetic packaging is mainly used for the packaging of high-speed optical devices for medium and long-distance transmission, so as to meet the requirements of long-term service life of the device. [0003] However, whether it is the aforementioned TO-CAN package or the BOX hermetic package, the coupling efficiency of the lens part in the component is very low. Taking a spherical lens as an example, the coupling efficiency of a ball with a slightly larger dia...
