Microcapsule‐Mediated Vibration‐Induced Emission for Real‐Time Visualization of Polymer Deformation
Advanced Optical Materials, EarlyView.A mechanochromic microcapsule is reported that combines vibration‐induced luminescence (VIE) with mechanically controlled release functionality. By embedding the microcapsules into a polymer matrix, the conformational changes of VIE molecules can be precisely amplified into visual fluorescent color signals, enabling real‐time, high‐sensitivity ...

An Efficient Diamond Raman Amplification Scheme Based on Adaptive Temporal Synchronization
Advanced Photonics Research, EarlyView.This work reveals an adaptive temporal synchronization effect in delayed diamond Raman amplification, where the Stokes pulse shifts toward the fundamental peak. A periodic amplification scheme based on this phenomenon enables efficient pump recycling and enhanced energy conversion, offering a robust, delay‐tolerant strategy for advanced nonlinear ...

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation
Advanced Photonics Research, EarlyView.Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.
