Two aspects of normal use and adjustment use are embodied, irregular rotation adjustment or orderly adjustment along the X axis, the Y axis and the Z axis are achieved, it is ensured that the optical fiber assembly is located and kept in a horizontalstate through use of the weighing column, and the supporting column and the limiting sleeve; meanwhile, the stress is uniform, and position deviation caused by gravity when the position is well adjusted is avoided.

Description

technical field [0001] The invention relates to the technical field of optical fiber coupled optoelectronic devices, in particular to various miniature optical fiber coupled optoelectronic devices and their assembly methods. Background technique [0002] Fiber-coupled optoelectronic devices are widely used in laser communication, fiber laser pumping, material processing and processing, etc. At present, fiber-coupled optoelectronic devices require very accurate positioning of the light-emitting chip, so that fiber coupling can have high coupling efficiency. [0003] At present, most fiber coupling adjustments are X / Y / Z three-dimensional adjustments, without angle adjustment. Even if the angle adjustment can be realized through an external adjustment bracket, it will make it difficult to fix the fiber optic components. For this reason, the Chinese patent discloses A miniature fiber-coupled optoelectronic device and its assembly method (patent number: CN104280842B), including a...

Problems solved by technology

[0003] At present, most fiber coupling adjustments are X / Y / Z three-dimensional adjustments, without angle adjustment. Even if the angle adjustment can be realized through an external adjustment bracket, it will make it difficult to fix the fiber optic components. For this reason, the Chinese patent discloses A miniature fiber-coupled optoelectronic device and its assembly method (patent number: CN104280842B), including a tube shell and a cover plate, a heat sink, a light-emitting chip, a shell connector, a spherical adjustment piece and a metal optical fiber assembly. The technical solution is suitable for optical fiber coupling of optoelectronic devices such as semiconductor lasers or solid-state lasers, and has the advantages of simple structure, convenient installation and operation, and long-term reliability.

[0004] However, whether it is the above-mentioned disclosed technical solution or the traditional technical solution, when adjusting, it will affect the optical fiber components connected and installed on it, that is, after the angle change or position change is completed, the position and position of the optical fiber components will also be affected. Changes will occur accordingly, so that in normal use, slight changes in position will be caused by the gravity of the fiber optic component itself, and it may also cause bending between the fiber optic component and the electrical device, regardless of the adjusted position. Or the safety of optical fiber components is affected to a certain extent. Therefore, how to change or control the impact of the above problems on electrical devices and optical fiber components is a major problem that is currently faced and needs to be solved.
