A photonic neural network chip

Abstract

An embodiment of the present invention provides a neural network chip, including: an optical input module, an optical processing module, and an optical output module. Wherein, the optical input module at least includes a wavelength division multiplexer, configured to receive multiple input optical signals, and multiplex the multiple input optical signals into one first target optical signal. The optical processing module is connected to the output end of the optical input module, and is used for calculating the first target optical signal to generate a second target optical signal. The optical output module is connected to the output end of the optical processing module, and at least includes a demultiplexer for decomposing the second target optical signal into multiple output optical signals. It can be seen that this solution performs wavelength division multiplexing on optical signals, and several optical signals are input to the optical processing module through light beams with different wavelengths, thereby increasing the information capacity of single-channel optical propagation, thereby increasing the calculation speed of the photonic neural network.

Description

technical field [0001] The invention relates to wavelength division multiplexing technology, in particular to a photonic neural network chip. Background technique [0002] At present, the artificial neural algorithm operated by the neural network chip includes a large number of matrix multiplication operations, and the computing platform of the traditional computer architecture (such as the computing platform composed of CPU or GPU) needs a large computing power when processing these operations. support. Specifically, it is necessary to use the calculation module to learn different operation logics in depth. However, the versatility of many operation logics cannot be completed efficiently, which in turn leads to low calculation efficiency.
