Problems solved by technology

[0003] The optoelectronic digital logic operation chip is an important component to realize optoelectronic intelligent computing. At present, there are many ways to realize the optical digital logic gate: the optical digital logic gate can be realized by non-linear devices such as semiconductor optical amplifiers, periodically poled lithium niobate waveguides, and electroabsorption modulators. Its unit calculation energy consumption, noise and other performance are not ideal, and the integration potential is limited; in terms of integrated optical computing, the representative work in the world mainly includes matrix numerical calculation based on silicon photonics optical interference network array, optical phase change material array Realize the integration of storage and calculation, etc. Similar work has realized some simple optical calculations, but the current silicon photonics scheme has problems such as low parameter scale and relatively simple model structure; the optoelectronic Fourier domain convolutional neural network based on space optics has realized High-throughput optical computing, but the system modulation rate is limited, and errors are difficult to correct

In related technologies, there is a lack of a logic operation device that can perform large-scale operations and has a high modulation rate, which needs to be solved urgently
