Embodiment Construction

[0024] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0025] see first figure 1 , figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention; the miniature fiber-coupled optoelectronic device in this embodiment includes a shell and a cover plate 11, a heat sink 12, a light-emitting chip 13, a housing connector 14, a spherical adjustment member 15, and a metal optical fiber assembly 16. First, the light-emitting chip 13 is welded to the upper surface of the heat sink 12 with high-temperature solder such as gold tin, and then the bottom surface of the heat sink 13 and the inner bottom surface of the tube shell 11 are welded with low-temperature solder such as lead-tin; the metal optical fiber assembly 16 It is a component assembled by welding and assembling the optical fiber after metallization. The end face of the optical fiber is a flat end and coated with an anti-reflection fi...

Description

technical field [0001] The invention relates to an optoelectronic device, in particular to a miniature optical fiber coupled optoelectronic device and its assembly method. 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. Moreover, most fiber coupling adjustments are X / Y / Z three-dimensional adjustments without angle adjustment. Even if the angle adjustment can be achieved through an external adjustment bracket, it will make it difficult to fix the fiber optic components. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing miniature fiber-coupled optoelectronic devices in the process of fiber coupling install...
