Description

technical field [0001] The invention belongs to the technical field of photonic signals, in particular to a photonic neural network chip. Background technique [0002] Photonic integration technology uses light as the carrier of transmission and processing, which can easily break through the bandwidth bottleneck of electronic technology and provide strong support for future ultra-large bandwidth and ultra-high-speed computing. Therefore, using photonic technology to implement a deep learning computing chip, that is, a neural network chip, has become a research hotspot. [0003] The Massachusetts Institute of Technology has developed a photonic neural network chip that can realize matrix multiplication by using coherent optics. However, the disadvantage of this method is also obvious. When the required calculation is more complicated, the chip realized by this method will be very complicated, and the number of cascaded photon phase shifters will be very large, which will aff...
