abstract = {Convolutional Neural Network（CNN）has shown a wide range of applications in the fields of face recognition, image classification, machine vision, medical imaging, and aerospace due to its excellent feature extraction capabilities. However, traditional electrical intelligent processing chips are restricted by Moore’s law, and is difficult to meet the continuous growth of CNN computing power demand. With its characteristics of ultra-large broadband and ultra-low loss, light wave is a disruptive technology that supports the high computing power demand of the next generation of artificial intelligence. With optical or electrical high-dimensional control structure as the basic unit, it can realize computing through controlled propagation of light. In this paper, the research progress and technological breakthroughs of optical convolutional neural networks are reviewed. The overall trend of their development and the technical problems that need to be solved in the future are summarized. The prospects of optical convolutional neural networks for application are also discussed.}
