Small Methods, EarlyView.This study demonstrates the detection of virus‐sized single polystyrene particles in water by leveraging the ultrahigh‐Q nature of low‐contrast bound states in the continuum (BIC) metasurfaces. The resonance properties of silicon BIC metasurfaces—wavelength, linewidth, and amplitude—all exhibit single‐particle sensitivity, representing a unique sensing

Nanophotonics, Volume 15, Issue 16, 26 August 2026.Based on the modified Langevin noise formalism and BA‐MA theory, optimized computational formulations are demonstrated for quantum plasmonic simulations without explicit BA–MA mode construction. Plasmonic Hong‐Ou‐Mandel interference, g2, atomic population, and single‐photon probability amplitudes are efficiently analyzed, revealing directional single ...

Low‐Loss Routing of Strongly Confined Light in Ultra‐Compact Silicon Slot‐Waveguide Bends
Nanophotonics, Volume 15, Issue 16, 26 August 2026.An ultra‐compact asymmetric silicon slot‐waveguide bend enables low‐loss routing of strongly confined light by compensating for curvature‐induced field displacement. The optimized rail‐width profile redistributes the optical field toward the outer rail and restores the slot‐confined mode at the output, achieving broadband quasi‐TE0 transmission in a 1 ...

Radiation‐Free In‐Gap Finite Barrier Bound States in a Lithium Niobate‐Based Honeycomb Lattice
Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work demonstrates radiation‐free finite barrier bound states (FBBSs), successfully overcoming the high propagation loss challenge inherent in conventional FBBS designs while enabling flexible electro‐optic tunability. These findings establish a versatile platform for on‐chip integrated, high‐modulation‐efficiency electro‐optic modulators and ...

Multiple Bound States in the Continuum in Deep‐Subwavelength Nonlocal Polar Dielectric Nanoparticles
Nanophotonics, Volume 15, Issue 15, 13 August 2026.Spatial dispersion in polar‐dielectric core–shell nanoparticles enable multiple deep‐subwavelength bound states in the continuum through longitudinal‐transverse hybrid modes. By suppressing radiative damping at finite geometrical parameters, these nonlocality‐induced BICs provide a compact platform for high Q light confinement, enhanced light–matter ...

Velocity‐Tunable Exciton‐Photon Hybridization in Cathodoluminescence
Advanced Functional Materials, Volume 36, Issue 62, 3 August 2026.Transition‐radiation resonances in suspended thin crystals hybridise with excitonic transitions under free‐electron excitation. By tuning the electron energy, the photonic resonances are continuously detuned across the exciton states, enabling controllable exciton–photon hybridisation below the diffraction limit without altering the system geometry ...
