Chip‐Integrated Metasurface‐GaAsSb Nanowire Array Photodetectors for Single‐Pixel Polarimetric Imaging

Advanced Optical Materials, EarlyView.
A 2×2 multiplexed GaAsSb nanowire photodetector array integrated with L‐shaped metasurfaces is developed for miniaturized infrared polarimetry. Leveraging non‐radiating anapole states that facilitate near‐field enhancement, the device demonstrates strong polarization selectivity at 835 nm.

A Proline‐Integrated Donor–Acceptor Fluorophore: Water‐Vapor‐Responsive Mechanochromic Luminescence and Latent Fingerprint Visualization

Advanced Optical Materials, EarlyView.
A proline‐integrated donor–acceptor fluorophore enables multifunctional luminescence through rational molecular design. Water‐vapor‐responsive mechanochromic luminescence (MCL) with circularly polarized luminescence (CPL) switching and efficient visualization of latent fingerprints (LFPs) are realized from this single small organic molecule.
