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

Ultrasensitive Tunable Terahertz Sensor via Critical Coupling‐Enhanced Fano Resonance

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This work presents a hybrid terahertz sensor via the combination of graphene‐strip metasurface, cavity resonance, and gold film polaritons. The sensor achieves critical coupling with an ultrahigh‐Q resonance and tunable FOM with stable high sensitivity via gate voltage regulation, exhibiting excellent performance for on‐chip integrated biochemical ...

Broadband and Wide‐Angle Nonreciprocal Electromagnetic Transport via Gradient Permeability‐Near‐Zero Metastructures

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
ABSTRACT Breaking time‐reversal symmetry to achieve broadband and wide‐angle nonreciprocity is critical in electromagnetic waves manipulation. While Epsilon‐Near‐Zero materials have revolutionized the control of Transverse Magnetic modes, realizing comparable broadband nonreciprocity for Transverse Electric (TE) modes remains a formidable challenge ...

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

Nanophotonics, Volume 15, Issue 9, -Not available-.
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.

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...

Nonlinear photonics in all-dielectric metasurfaces

, 2016
The presentation surveys the results on the studies of the nonlinear-optical effects in different types of novel planar metamaterials utilizing Mie-type dielectric resonances. First, we discuss the observation enhanced third-harmonic generation from silicon nanodisks exhibiting both electric and magnetic dipolar resonances [1].
