Abstract

The invention provides a method for debugging the wavelength of an optical module by using astigmatism. The optical module comprises a plurality of lasers, an optical multiplexer for combining the light of the plurality of lasers into one path and an optical fiber adapter coupled with the optical multiplexer, and the method comprises the following steps of (1) fixing the lasers, the optical multiplexer and the optical fiber adapter; and then obtaining the wavelength of each laser; (2) comparing the obtained wavelength of each laser with the corresponding central wavelength to obtain a difference value between the wavelength and the central wavelength; (3) acquiring an average value of the difference values between the wavelengths of the lasers and the central wavelength, and acquiring a compensation temperature corresponding to the average value of the wavelength difference values according to a change corresponding relation between the temperatures of the lasers and the wavelengths; and (4) compensating the temperature of each laser through a semiconductor cooler according to the compensation temperature. According to the present invention, the repair cost and time are prevented from being increased, the production cost and difficulty are prevented from being increased, and the debugging method is simple.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a method for adjusting the wavelength of an optical module by using astigmatism. Background technique [0002] Optical modules are an important part of building optical communication systems, and play a key role in the development of 5G communication and data centers. The development and application of high-speed, long-distance optical transmission equipment and intelligent optical networks are closely related to the technological progress of optoelectronic devices. The main function of the module is to realize photoelectric conversion and then realize the transmission of information. [0003] Lasers with different wavelengths can be emitted by using semiconductor lasers, and then the transmission of optical signals can be realized by adjusting the optical path. Due to the complex working environment of the optical module, changes in temperature can eas...
