Problems solved by technology
[0004] However, in the process of realizing the present invention, the applicant finds that the existing optical vector-matrix multiplier has the following problems: due to the deficiencies in the device process and the characteristics of the device itself, the optical vector-matrix multiplier needs lasers, detectors, etc. Many performance inconsistencies will be introduced when the optical device and modulator matrix are working. Different laser paths have different output powers for the same input vector, which affects the stability and accuracy of the entire optical vector-matrix multiplier operation performance.

The invention provides a method for rectifying consistency of optics vector quantity-matrix multiplying unit laser path. Parameters of other laser paths are marked and rectified through a basic laser path, so that inconsistency of output light intensity of each laser path corresponding to the same input vector quantity is solved, and the inconsistency is caused by inconsistency of character parameters.
Description
technical field [0001] The invention relates to the technical fields of optical information processing and optical calculation, in particular to a method for correcting the consistency of laser paths of an optical vector-matrix multiplier. Background technique [0002] With the development of science and technology and the improvement of people's living standards, more and more information has to be processed, and there are higher requirements and standards for real-time and accuracy. Since the birth of the first computer, people have been pursuing the improvement of computing performance, new technological levels have emerged, and new computer hardware structures have been proposed, such as dedicated DSP for digital signal processing, customized integrated circuits, And programmable logic devices (FPGA), but this is still far from meeting the needs of the rapid development of current applications. [0003] Due to the limitations of electrical information processing in term...
