Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

Small, EarlyView.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

Waveguide‐Based Four‐Channel Crosstalk‐Free Metahologram Multiplexed by Diffraction Orders

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A diffraction‐order‐multiplexed, four‐channel metahologram integrates a flat glass waveguide and an array of titanium dioxide nanopillars to realize crosstalk‐free holographic projection. Light undergoes total internal reflection within the waveguide and gets out‐coupled by diffraction from the nanopillar array.

Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

Interference‐Induced Cavity Resonances and Imaginary Rabi Splitting

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Coupling of a two‐level emitter to (a, b) a single‐mode resonance with a Lorentzian spectral density, and (c, d) a two‐mode cavity with a more complex spectral density. This work reveals a new polaritonic regime beyond the single‐mode description, emerging from emitter interaction with the interference‐induced resonance associated with the Fano ...

One‐Step Fabrication of Non‐Ablative Microstructures for Efficient Second Harmonic Generation on LiNbO3 Thin Film

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This study presents a novel one‐step femtosecond laser modification technique for fabricating high‐quality periodic metasurfaces on lithium niobate thin films without surface damage and scattering centers. Under oblique incidence at 1030 nm, a 4.75‐fold enhancement in second‐harmonic generation efficiency is achieved through complementary mechanisms ...

Electrically Reconfigurable Quasi‐BIC Metadevices Enabled by Integrated Barium Titanate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
An electrically reconfigurable quasi‐BIC metasurface is demonstrated by monolithic integration of barium titanate. Leveraging the Pockels effect, linear tuning of 1.79 nm/V is achieved, enabling a 250 μm2 miniaturized spectrometer with 0.2 nm resolution, 99% fidelity, and high throughput.

Giant Circular Dichroism in Chiral Broad Flat‐Band Quasi‐BIC Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Tuning the near‐field coupling between adjacent nanopillars gradually flattens the photonic band. Reducing the interpillar spacing strengthens mode hybridization, yielding an ultraflat dispersion that hosts a high‐Q quasi‐BIC. This work delineates the physical mechanism linking structural parameters to flat‐band formation, enabling giant circular ...

Direction finding by learning-assisted programmable metasurface

Journal of Applied Physics
This study explores the assistance of supervised machine learning to a programmable metasurface for precise direction finding. The programmable metasurface plays the role of an electronic-scanning reflector to scan the azimuth plane and redirect incident waves toward a single radio frequency receiver, which records the power level of the incoming ...
