Hanqing Zhu, Jun Zou, Hui Zhang, Hong Nian Cai, A. Q. Liu · Conference on Lasers and Electro-Optics · 2022
A the integrated diffractive optical network for implementing parallel Fourier transforms, convolution operations and application-specific optical computing is demonstrated and achieved ~10-fold reduction in both footprint and energy consumption. It has high potential in optical-artificial-intelligence.
