Edge-enhanced diffractive neural networks based on spin-multiplexed nonlocal metasurfaces

Single-layer diffractive neural networks often face classification accuracy bottlenecks due to limited wavefront modulation capabilities. Edge detection, as an optical image processing technique, extracts image contours and offers a promising way to simplify classification tasks....

Deep Neural Network Enabled Complex‐Amplitude Metasurfaces for Simultaneous Nanoprinting and Holography

ABSTRACT Metasurfaces offer a compact and scalable platform for multidimensional optical field manipulation and engineering. By judiciously designing subwavelength scatterers to tailor the complex transmitted field, a single metasurface can encode a prescribed near‐field distribu...
