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.

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...
