From Nano‐ to Picocavities: The Role of Atomistic Features

Small Structures, Volume 7, Issue 10, October 2026.
Atomistic features strongly affect the plasmonic response of Ag and Au nano‐ and picocavities. By analyzing induced charge densities, electric field maps, and localization areas, the role of atomistic morphology in controlling field confinement and enhancement is revealed, establishing a direct structure–property relation between atomic‐scale features ...

Polymer Brushes Govern Defect‐Selective Oxidative Etching of Penta‐Twinned Gold Nanorods

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Polymer brushes act as active interfacial regulators of oxidative etching, directing it to crystallographic defects. In penta‐twinned gold nanorods, defect–ligand interplay localizes etching to defect regions and induces surface corrugations on the long nanorod sides. This work establishes a framework for programmable nanoengineering of the surfaces of

Triple Space‐Polarization On–Off‐Key Modulation With AlN‐Based Tri‐Focal Metalens

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
An AlN tri‐focal metalens made of high‐temperature‐annealed AlN by integrating zone‐plate null rings into a polarization‐selective bifocal metalens. The incident light will be focused into two or three foci on the focal plane, each with a distinct polarization state.

Multi‐Objective Inverse Design of a Dual‐Narrowband Thermal Emitter for Optical Gas Sensing

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
A lithography‐free, wafer‐scale dual‐narrowband thermal emitter is developed using a multi‐objective inverse design framework. It comprises an aperiodic Si/SiO2 dielectric multilayer deposited on a TiN refractory conductive ceramic film. Its dual emission peaks match characteristic absorption bands of CH4 and NO2 and enhance responses to both gases ...

Large Rabi Splitting Driven by Plasmon‐Enhanced Hybrid Anapole States in Si–Au–WSe2 Heterostructures

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
A silicon hybrid‐anapole microcavity coupled with a plasmonic array enables tripartite strong coupling with WSe2 excitons. Spatially extended field enhancement and coherent cavity–plasmon hybridization strengthen light–matter interactions, producing a giant 330 meV Rabi splitting at room temperature and offering a compact platform for low‐exciton ...

Decoupled Spectral Tuning and Polarization Locking in Twisted α $\alpha $‐MoO3 Polaritonic Crystals

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
We introduce a deterministic design strategy employing twisted bilayer α $\alpha $‐MoO3 ${\text{MoO}}_{3}$ polaritonic crystals to decouple infrared spectral and polarization degrees of freedom. Although adjusting the interlayer twist angle tunes the absorption spectra, the maximum absorption axis remains robustly locked to the patterned layer's ...

Design of Large‐Aperture Hybrid Refractive Metalens System

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

Surrogate Scattering Matrix‐Guided Inverse Design of Nanophotonic Neural Networks

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Surrogate‐guided inverse design separates task learning from electromagnetic realization by transferring a trained passive operator to a fabrication‐aware nanophotonic structure. The electromagnetic cost of each update depends on port count rather than the dataset size.
