Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence

Advanced Science, Volume 13, Issue 9, 13 February 2026.
An innovative dual‐spectroscopy approach resolves the debate over GaAsBi's emission temperature sensitivity. By combining temperature‐dependent photoluminescence and transmission spectroscopy, the method decouples the contributions of band‐tail states from the intrinsic band‐edge behavior.

High‐Sensitivity, High‐Resolution Stimulated Raman Photoacoustic Spectroscopy Enabled by Continuous‐Wave Intracavity Pump‐Stokes Beams

Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.
High‐sensitivity, high‐resolution stimulated Raman photoacoustic spectroscopy is achieved by coupling continuous‐wave pump and Stokes beams to a high‐finesse optical cavity. This approach successfully resolves the narrow Raman rotational transition S0(0) of H2 with sub‐kHz spectral resolution and attains an unprecedented sensitivity of 0.5 ppm using ...

Quantum Theory of Surface Lattice Resonances

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
ABSTRACT The collective interactions of nanoparticles arranged in periodic structures give rise to high‐Q $Q$ in‐plane diffractive modes known as surface lattice resonances. Although these resonances and their broader implications have been extensively studied within the framework of classical electrodynamics and linear response theory, a quantum ...
