Noise Resilient Real‐Time Phase Imaging via Undetected Light

Advanced Quantum Technologies, Volume 9, Issue 7, July 2026.
Quantum imaging with undetected light enables decoupled illumination and detection, but real‐time operation under strong noise conditions remains challenging. By combining nonlinear interferometry with off‐axis holography, this work demonstrates real‐time amplitude and phase imaging at up to 4 Hz, even when noise exceeds the signal by an order of ...

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

Small, Volume 22, Issue 37, 2 July 2026.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

Three‐dimensional Microstructuring of Chalcogenide Glass by Femtosecond Laser Exposure and Subsequent Chemical Etching

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Chalcogenide glass has the broadest reported transparency in the infrared, making them particularly attractive for spectroscopy and infrared imagery. Yet, it remains a difficult material to shape in arbitrary form. In this paper, we explore the combination of femtosecond laser‐exposure and subsequent chemical etching steps to produce arbitrary

Infrared‐Microwave Compatible Stealth Transparent Metasurface With Digital Camouflage and Hybrid Absorption‐Scattering

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).

Transmissive Terahertz Tunable and Multifunctional Polarization Manipulation With Ge/VO2 Hybrid Metasurface

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
A hybrid metasurface composed of Ge dielectric pillars and a VO₂ grating is proposed, which enables functional switching between symmetric and asymmetric polarization conversion in transmission. By continuously tuning the conductivity of VO2, the structure achieves multiple dynamic controls of asymmetric transmission, circular dichroism, and ...
