Patent number: 12229662Abstract: An all-optical neural network that utilizes light beams and optical components to implement layers of the neural network is disclosed herein. The all-optical neural network includes an input layer, zero or more hidden layers, and an output layer. Each layer of the neural network is configured to simulate linear and nonlinear operations of a conventional artificial neural network neuron on an optical signal. In an embodiment, the optical linear operation is performed by a spatial light modulator and an optical lens. The optical lens performs a Fourier transformation on the set of light beams and sums light beams with similar propagation orientations. The optical nonlinear operation is implemented utilizing a nonlinear optical medium having an electromagnetically induced transparency characteristic whose transmission of a probe beam of light is controlled by the intermediate output of a coupling beam of light from the optical linear operation.Type: GrantFiled: April 14, 2020Date of Patent: February 18, 2025Assignee: THE HONG KONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Shengwang Du, Junwei Liu, Ying Zuo, Bohan Li, Yujun Zhao, Yue Jiang, Peng Chen, You-Chiuan Chen
