Graphical Abstract 3D Photonic Device for Spatial Mode Bases Mapping On-chip angle-robust computational spectral imaging based on topology-optimized plasmonic metasurfaces is proposed and experimentally reported in article number 2400255 by Kaiyu Cui, Yidong Huang, and co-workers. The fidelity of spectral reconstruction realized by an auto-encoder is over 98% under a 30° field-of-view, and spectral imaging for a standard color checker is demonstrated.

AbstractMetasurfaces with tunable functionalities are greatly desired for modern optical system and various applications. To increase the operating channels of polarization-multiplexed metasurfaces, we proposed a structure of N cascaded dual-channel metasurfaces to achieve 2N electrically switchable channels without intrinsic loss or cross-talk for certain functionalities, including beam steering, vortex beam generation, lens, etc.

AbstractThe photonic Ising machine is a new paradigm of optical computing that takes advantage of the unique properties of light wave propagation, parallel processing, and low-loss transmission. Thus, the process of solving combinatorial optimization problems can be accelerated through photonic/optoelectronic devices, but implementing photonic Ising machines that can solve arbitrary large-scale Ising problems with fast speed remains challenging.
