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 ...

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

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 ...

Polarization‐Independent Single‐Band Guided‐Mode Resonance InGaAs Photodetector Array for Snapshot Multispectral Sensing

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Here, we report a single‐band guided‐mode resonance (GMR) InGaAs photodetector (PD) array. The device consists of an InGaAs PD with an ultrathin absorption layer bonded onto a Si 2D grating. Although a 2D crossed‐grating inherently supports many more optical modes than a 1D grating, we realized a single‐band response by introducing novel design ...
