Laser &Photonics Reviews, EarlyView.Bi3+‐doped Cs2SnCl6 nanocrystals are engineered to deliver highly temperature‐responsive self‐trapped exciton emission, achieving record thermal sensitivity at elevated temperatures. A temperature‐induced dual‐STE excited state landscape enables reversible thermochromism, while a dual‐parameter calibration combining fluorescence lifetime and CIE‐y ...

Multispectral Concentric Grafted Perfect Vector Vortex Beam
Laser &Photonics Reviews, EarlyView.Multispectral structured light offers powerful opportunities for increasing information capacity. A multispectral concentric grafted perfect vector vortex beam is proposed to engineer topological charges and polarization. A metasurface can graft different perfect vector vortex beams across concentric spatial regions and extend this concept to ...

Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs
Laser &Photonics Reviews, EarlyView.The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Unified Full‐Stokes Polarimetry and Orbital Angular Momentum Metrology Leveraging Isotropic D2NN
Laser &Photonics Reviews, EarlyView.Here, we propose a versatile isotropic deep diffractive neural network (D2NN) framework to transcend these limitations. Our results show that, using a single phase‐only mask, the D2NN‐based detection geometry achieves an ultrahigh accuracy in full‐Stokes retrieval and an extremely low error in orbital angular momentum spectrum reconstruction, coupled ...
