Keywords:

Photonics in neuromorphic computing and machine learning devices,Highly parallelized scalable photonic computing architectures and devices

We proposed an in-situ unsupervised learning method for training optical diffraction neural networks. Once deployed, our network achieved an image recognition accuracy of 88.37% without image labels or human intervention.
