2021 IEEE Photonics Society Summer Topicals Meeting Series (SUM) | 2021
Integrated metasystem for image recognition
Abstract
With lithographically defined inter-layer alignment, we demonstrate diffractive deep optical network on silicon photonic platform, towards broadband spatial pattern classification and hyperspectral imaging. The high-throughput vector-by-matrix multiplications is enabled by 103 passive subwavelength phase shifters as weight elements.
