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.

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

Influence of Fano resonance on SERS enhancement in Fano-plasmonic oligomers

Optics Express, 2019
Plasmonic oligomers can provide profound Fano resonance in their scattering responses. The sub-radiant mode of Fano resonance can result in significant near-field enhancement due to its light trapping capability into the so-called hotspots. Appearance of these highly localized hotspots at the excitation and/or Stokes wavelengths of the analytes makes ...

Wavefront Selective Modal Excitations for Optimally Informative Sensing in Fano‐Resonant Metasurfaces

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Structured illuminations can unlock hidden quasi‐BIC modes in Fano‐resonant metasurfaces, enhancing the sensitivity to nanoscale perturbations. By analyzing the eigenmode spectrum of a dielectric metasurface and applying information theory, tailored wavefronts can be engineered that selectively excite otherwise inaccessible modes.
