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 emitting device using the medium, wherein the medium has a computer program stored therein, and the computer program can be executed by a processor of the laser coupling device. Coupling in a three-dimensional rectangular coordinate system in which the horizontal displacement direction of the light in a multiplexer Mux is the X-axis direction is carried out; at first, the fixed position of a collimator is confirmed by collimator lenses of the first channel and the fourth channel at a collimator position with the coupling power greater than the preset value M,and then the collimator lenses of the four channels are coupled one by one and fixed to the position with the coupling power greater than the preset value N to complete the coupling. When coupling ofeach channel is carried out, an operator only needs to pay attention to the position change of each channel relative to the collimator which has been fixed, and does not need to adjust according to the previous laser coupling result, so that coupling is faster and more effective.
Description
technical field [0001] The present 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 for a four-channel wavelength-division multiplexing optical emission 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 to me...
