Advanced Optical Materials, Volume 13, Issue 19, July 4, 2025.Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...

Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology
Advanced Photonics Research, EarlyView.This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Stimulated Raman Scattering with Optical Vortex Beams
Advanced Photonics Research, EarlyView.This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.

Polarization Management on Anisotropic Thin‐Film Lithium Niobate Platform
Advanced Photonics Research, EarlyView.This review focuses on x‐cut thin‐film lithium niobate (TFLN), exploring strategies to mitigate anisotropy and mode hybridization. It covers polarization beam splitters, rotators, splitter‐rotators, polarizers, and polarization‐insensitive components. Key applications include polarization‐division multiplexing, polarization‐insensitive modulation, and ...
