Optical module packaging method, optical module and optical transmitter

Abstract

The invention provides an optical module packaging method, an optical module and an optical transmitter. The optical module comprises a substrate, at least two lasers, at least two first adjusting lenses, an optical multiplexer, a second adjusting lens and an optical fiber adapter. The first adjusting lenses are arranged on an emitting light path of the laser; the first adjusting lenses are in one-to-one correspondence with the lasers; the optical multiplexer is used for combining the emergent light of the first adjusting lenses into one path of light beam; the first adjusting lens is arrangedon an emergent light path of the optical multiplexer; the optical fiber adapter is arranged at an emergent light path of the second adjusting lens; and the laseres, the first adjusting lenses, the optical multiplexer, the second adjusting lens and the optical fiber adapter are fixedly arranged on the substrate. According to the packaging method of the optical module, the optical module and the optical transmitter, the number of devices needing to be actively fixed can be reduced, the packaging process of the optical module can be simplified, the production efficiency is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module packaging method, an optical module and an optical transmitter. Background technique [0002] In recent years, the technology of multiplexing multiple wavelengths of light directly in optical modules and then transmitting them in optical fibers has become more and more widely used. Typical products such as 4*10G, 4* 25G optical modules and 4*50G and 4*100G optical modules whose shipments are currently growing rapidly. Compared with the traditional coaxial optical module, the multiplexed optical module has a complex structure and more difficult design, and the difficulty of optical coupling is also higher. Among them, what kind of optical coupling method will directly determine the success rate of optical coupling and the yield rate of optical modules. [0003] refer to figure 1 , figure 1 It is a schematic diagram of an optical module in the pr...
