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.

Interaction of Structured Light With Nanostructured Matter

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Structured light–matter interactions at the nanoscale remain poorly understood. We reveal a symmetry‐matched mechanism governing orbital‐angular‐momentum‐dependent extinction in gold nanodisk oligomers. Tailored diffractive optical elements generate flower‐like beams whose rotational symmetry dictates absorption. Experiments and a semi‐analytical model

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 ...

Reciprocal Quantum Electrodynamics With Bound States in the Continuum

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Quantum electrodynamics accurately describes all known forms of modern optics and photonics regarding interactions between photons and matter. In this context, bound states in the continuum with photon confinement in momentum space are envisioned to open an exciting branch called reciprocal quantum electrodynamics. It complements the cavity counterpart

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.
