Wherein adjusting the position of the second conditioning lens 140 includes moving and rotating the second conditioning lens 140. When the laser 110 is powered on, the light from the laser 110 can be split into a plurality of beams, each beam has different coupling efficiency by coupling into the adapter through the lens, and only the beam near the optical path with the best coupling efficiency has the highest coupling efficiency, so that the position with the best coupling efficiency, that is, the position of the second adjusting lens 140 when the optical power output by the adapter is the maximum, can always be found by adjusting the position of the second adjusting lens 140.
Preferably, adjusting the position of the second adjusting lens 140 includes positioning the second adjusting lens 140 at a predetermined distance from the fiber adapter 150, and then adjusting the position of the second adjusting lens 140 in two directions perpendicular to the optical axis until the optical power output by the fiber adapter 150 reaches a maximum. Wherein the predetermined distance is a focal length of the second adjusting lens 140. For example, the focal length of the second adjusting lens 140 is 2mm, and the distance from the second adjusting lens 140 to the adapter can be controlled to be 2 ± 0.3 mm.

Step S004, powering on any laser 110, adjusting the position of the first adjusting lens 120 corresponding to the laser 110 in the light emitting state of the laser 110 until the optical power output by the optical fiber adapter 150 reaches a target value, and then fixing the first adjusting lens 120. Wherein adjusting the position of the first conditioning lens 120 includes moving and rotating the first conditioning lens 120.

Step S005, repeats step S004 until all the first adjustment lenses 120 are fixed.
Step S006, place the optical module into an oven to further cure the glue.
The following describes a method for packaging an optical module by taking a 4-way multiplexed optical module as an example. The packaging method of the optical module comprises the following steps:
in step S101, an optical multiplexer 130, an optical fiber adapter 150, and four lasers 110 are fixedly disposed on a substrate. Wherein the laser 110, the optical multiplexer 130 and the fiber adapter 150 are passively fixed on the substrate.
Step S102, power up one laser 110, set the second adjusting lens 140 at a predetermined distance from the fiber adapter 150 in a state that the laser 110 emits light, and adjust the position of the second adjusting lens 140 in two directions perpendicular to the optical axis until the optical power output by the fiber adapter 150 reaches a maximum. Wherein the predetermined distance is a focal length of the second adjusting lens 140.
Step S103, individually powering up the other three lasers 110, and detecting the optical power output by the optical fiber adapter 150 when the other lasers 110 are powered up, if the difference between the optical power output by the optical fiber adapter 150 and the optical power output by the optical fiber adapter 150 when the first laser 110 is powered up is within a predetermined range, fixing the second adjusting lens 140, if the difference is beyond the predetermined range, repeating the above steps S101 and S102, and if the difference is still beyond the predetermined range, failing to optically couple. Wherein the predetermined range is 5 dbm.
Step S104, power up is applied to one laser 110 of the four lasers 110, and the position of the first adjusting lens 120 corresponding to the laser 110 is adjusted until the optical power output by the optical fiber adapter 150 reaches a target value, and then the first adjusting lens 120 is fixed.
Step S105, repeat step S104 until all four first adjusting lenses 120 are fixed.
And step S106, putting the optical module into an oven to further solidify the glue.
The active in the above embodiments means that the laser 110 is powered on, and the passive means that the laser 110 is not powered on.
Compared with the prior art, the invention has the following advantages:
firstly, in the optical module, the optical transmitter and the optical module packaging method of the present invention, the laser 110, the optical multiplexer 130 and the optical fiber adapter 150 are fixedly arranged on the substrate in the packaging process, then the position of the second adjusting lens 140 is adjusted and fixed, and then the position of the first adjusting lens 120 is fixed.
In addition, the conventional optical coupling method has a very high requirement on the mounting accuracy of the laser 110, and the mounting accuracy of the laser 110 is usually required to be within +/-20 um. Meanwhile, the requirement on the collimation angle of the collimating lens is very high, the angle between each path of collimated light and the designed light path is required to be within 0.5 degrees, the angle error of the collimating lens assembled on the substrate is required to be not more than 0.5 degrees if the angle between each path of collimated light and the designed light path is required to be within 0.5 degrees, and the substrate is required to have a small calibration error.
Secondly, in the optical module, the optical transmitter and the optical module packaging method, the laser 110, the optical multiplexer 130 and the optical fiber adapter 150 are fixedly arranged on the substrate in a passive mode in the packaging process, and then the second adjusting lens 140 and the first adjusting lens 120 are fixed in an active mode. Furthermore, there is a need in the art to check whether the converging lens can converge collimated light to a point in an active manner. Specifically, an optical fiber needs to be installed at a standard position, collimated light is coupled into the optical fiber by adjusting the position of the converging lens, and then the position of the converging lens is fixed. Meanwhile, in the prior art, the position of the optical fiber adapter 150 needs to be adjusted to be optically coupled with the converging lens under the active condition, and the optical fiber adapter 150 can be fixed in a passive mode in the invention, so that the optical coupling process can be simplified, and the production efficiency can be improved.
In addition, in the optical module, the optical transmitter and the optical module packaging method, the optical power of the optical fiber adapter 150 is monitored in the optical coupling process instead of the light spot penetrating through the optical fiber adapter 150, so that the structure of optical coupling equipment is greatly simplified, and the difficulty of the packaging process is reduced.
Thirdly, the existing optical coupling mode needs to be coupled with the converging lens by adjusting the position of the adapter, which causes that the light spots finally converged by the multipath light cannot be simultaneously positioned at the center of the fiber core of the fiber adapter 150, and if the light spots of one or more paths of light are positioned at the edge of the fiber core, the light path changes slightly when the optical module works at different temperatures, which causes that the output light power of the adapter changes greatly, thereby causing the problem of transmission failure. The optical module, the optical transmitter and the optical module packaging method adjust the position of the first adjusting lens 120 by directly monitoring the optical power of the output light of each path, so that the optical power of each path of light can be adjusted to the state of the maximum optical power, light spots of each path can be well coupled to the center of the fiber core of the adapter, and the stability of the optical path can be ensured.
Before the second lens adjusting mirror is fixed, the optical module, the optical transmitter and the optical module packaging method can detect the difference between the optical power output by the optical fiber adapter 150 when each laser 110 is powered on and the optical power output by the optical fiber adapter 150 when the first laser 110 is powered on, so that defective products can be found in advance, the packaging efficiency is improved, and the yield of the optical module is improved.
Thirdly, if the optical power of the optical module and the optical transmitter in the invention does not reach the standard, only the positions of the first adjusting lens 120 and the second adjusting lens 140 need to be adjusted, and all the lenses and the optical fiber adapters 150 do not need to be disassembled and assembled, so that the optical module and the optical transmitter can be repaired conveniently.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
