Software‐Defined Terahertz Beam Manipulation via Active Light‐Controlled Frequency Coding Information Metasurface

Advanced Physics Research, EarlyView.
This paper proposes an integrated active light‐controlled frequency coding metasurface and a software‐defined array control system. Utilizing spatially encoded structured light and a “Decision‐Optimization‐Execution” intelligent closed‐loop architecture, the system overcomes traditional electrical control interference, achieves real‐time dynamic ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.
