Abstract

The embodiment of the invention provides a coupling method for a light emitter and the light emitter, and relates to the technical field of optical communication. According to the coupling method forthe light emitter and the light emitter, the coupling process of the light emitter can be simplified, the coupling time can be saved, and the production cost can be lowered. The method comprises the following steps of carrying out passive fixation on a laser, an optical multiplexing component and an optical fiber adapter firstly and then adjusting the positions of a first lens and a second lens inan active environment so as to complete coupling assembly of the light emitter. The method is applied to production and assembly of the light emitter.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a coupling method and assembly equipment of an optical transmitter. Background technique [0002] In the field of high-speed data communication, the technology of micro-optics assembly is more and more widely used. Such as figure 1 It is a schematic structural diagram of a typical multiplexed optical transmitter, in which the optical transmitter mainly includes 4 lasers, 4 collimating lenses, an optical multiplexing component that combines 4 channels of light into 1 channel of light, a focusing lens, a Fiber optic adapter, in which 4 lasers can emit laser light with different wavelengths. The basic working principle of the optical transmitter is: 4 lasers emit 4 different wavelengths of light, which become 4 parallel collimated lights through 4 collimating lenses, and 4 parallel collimated lights are synthesized by an optical multiplexing component 1 way of light...
