Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures
Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

A Multi‐Dimensional Cathodoluminescence Detector With 3D Printed Micro‐Optics on a Fiber
Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.A fiber‐based cathodoluminescence (CL) spectroscopy detector is realized by printing a micro‐optical lens directly onto the fiber's facet using two‐photon polymerization. This compact collection scheme enables efficient CL acquisition across complex sample geometries, offering simplified alignment, modular integration, and access to spatially resolved ...

Increased rise time of electron temperature during adiabatic plasmon focusing
Nature Communications, 2017 Knowledge of the electron-gas dynamics in nanometric hot spots is of importance for hot-carrier technologies. Here Lozan et al. present a theoretical and experimental analysis of the spatio-temporal dynamics of hot electrons in a nano-focusing surface ...

Single-cycle surface plasmon polaritons on a bare metal wire excited by relativistic electrons
Nature Communications, 2016 Here, the authors demonstrate how ultra-short bunches of relativistic electrons produce coherent transition radiation at the tip of a thin wire. The radiation then propagates as a powerful surface plasmon polariton along the wire, illustrating the ...

Rabi-like splitting from large area plasmonic microcavity
AIP Advances, 2017 Rabi-like splitting was observed from a hybrid plasmonic microcavity. The splitting comes from the coupling of cavity mode with the surface plasmon polariton mode; anti-crossing was observed alongside the modal conversional channel on the reflection ...

Surface plasmon polaritons on curved surfaces
Optica, 2019 While the motion of a classical particle bounded to a surface depends only on the local curvature, the dynamics of a quantum particle depends also on the mean surface curvature. Its influence can be experimentally observed using surface plasmon polaritons (SPPs), which are naturally surface-bounded waves. Owing to the similarity between the Schrodinger
