High‐Transmission Mid‐Infrared Bandpass Filters using Hybrid Metal‐Dielectric Metasurfaces for CO2 Sensing

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This article presents a hybrid metal‐dielectric metasurface in transmission mode for mid‐infrared (MIR) spectroscopy. Composed of germanium on aluminium cylinders atop a calcium fluoride substrate, the metasurface achieves 80% transmission efficiency at λ = 2.6 µm with a narrow full‐width‐half‐maximum of 0.4 µm.

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 ...

Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

Advanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...
