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.

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.

Data‐Efficient Electromagnetic Surrogate Solver Through Dissipative Relaxation Transfer Learning
Advanced Optical Materials, EarlyView.Dissipative relaxation transfer learning (DIRTL) enables data‐efficient training of electromagnetic surrogate solvers by pretraining data generated with artificial material loss before fine‐tuning on target lossless data. The framework suppresses resonant outlier effects during early training, allowing effective adaptation to high‐amplitude resonances ...

Color Center Formation in Silicon‐On‐Insulator for On‐Chip Photonic Integration
Advanced Optical Materials, EarlyView.ABSTRACT Color centers in silicon have great potential as single photon sources for quantum technologies. Some of them – like the T center – also possess optically‐active spins that enable spin‐photon interfaces for generating entangled photons and multi‐spin registers. This paper explores the generation of several types of color centers in silicon for
