Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

Advanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Breaking Crystallinity for Optimal Dark Current: Nonfullerene Acceptor Dilution as a Strategy for High‐Performance Organic Photodetectors

Advanced Optical Materials, EarlyView.
Organic photodetectors (OPDs) based on polymer donor:non‐fullerene‐acceptor (NFA) bulk heterojunction blends offer strong light‐sensing potential, but require methods for optimization. This work demonstrates NFA dilution as an effective strategy to suppress dark current and enable state‐of‐the‐art performance by disrupting NFA crystallinity.
