Problems solved by technology
Most of the existing coupling methods are to arrange the collimator lens, multiplexer and collimator in sequence, and then perform coupling one by one according to the position of each channel. The speed is slow and if the coupling process of the front channel changes, each subsequent Channels must be adjusted against each other, and the adjustment range is too large

The invention relates to the technical field of four-channel wavelength division multiplexing, in particular to a computer readable storage medium and a laser coupling device of a four-channel wavelength division multiplexing optical receiver device applying the same. A computer program is stored in the medium, and the computer program can be executed by a processor of the laser coupling device. Coupling is carried out in a three-dimensional rectangular coordinate system with the horizontal displacement direction of light in a demultiplexer DeMux being the X-axis direction, firstly, a collimating lens of a first channel and the collimating lens of a fourth channel are used for confirming the fixed position of a collimator at the collimator position with the coupling power larger than a preset value M, then, the collimating lenses of the four channels are coupled one by one and fixed to a position having the coupling power greater than a preset value N, and the coupling is completed. When each channel is coupled, only the position change of the channel relative to the collimator with the fixed position needs to be focused without the need for carrying out contrast adjustment according to a result of previous laser coupling, and the coupling is more rapid and effective.
Description
technical field [0001] The present invention relates to the technical field of four-channel wavelength division multiplexing, and in particular to a computer-readable storage medium and a laser coupling device for a four-channel wavelength division multiplexing optical receiving device using the medium. There is a computer program stored in the medium, and the computer program It can be executed by the processor of the laser coupling device. Background technique [0002] With the rapid development of the Internet, big data, artificial intelligence, and high-definition television, the demand for optical fiber network transmission rates is getting higher and higher. Humans use various methods to increase the transmission rate of optical fiber networks. Limitations on materials and upgrade rates lead to a slow increase in the rate of the chip itself. At present, the main chips only support 25G, which still cannot meet the market's requirements for transmission rates. In order ...
