Fano resonance in concentric ring apertures
Optics Express, 2013 We demonstrate a polarization-independent mid-infrared Fano resonance with extraordinary transmission when light passes through two concentric metallic ring apertures. A high-Q dark mode is indirectly excitated by coupling with a low-Q bright mode. A coupled optical resonator model is used to analyze the coupling process between the bright and dark ...

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 ...

Polaritonic Spectra of Optical Mie Voids
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Optical Mie voids have been shown to provide a versatile platform for polaritonic physics. Analytical and numerical analysis reveal how void resonances couple to excitonic media, enabling weak‐ and strong‐coupling regimes, polariton gaps, Q‐factor enhancement, and spatial mode localization.

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 ...
