Nanophotonics, Volume 15, Issue 17, 11 September 2026.Inverse‐designed nanophotonic structures on a foundry‐compatible silicon nitride chip enable efficient in‐plane green excitation and broadband red emission extraction from diamond nitrogen‐vacancy centers. A compact emitter triples the guided optical power, while a directional coupler routes ∼80% of the fluorescence to detection, advancing miniaturized

Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array
Nanophotonics, Volume 15, Issue 17, 11 September 2026.A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.

Vectorial Diffractive Neural Metasurfaces for Multiplexed Synthesis of Optical Skyrmions
Nanophotonics, Volume 15, Issue 17, 11 September 2026.A three‐layer Jones‐matrix‐based vectorial diffractive neural network enables compact, passive, and multiplexed synthesis of optical skyrmions and bimerons. By mapping distinct Gaussian‐beam input channels to coaxial orbital‐angular‐momentum and polarization states, the device generates up to 16 topological vector textures with high mode purity, robust

Nanophotonics, Volume 15, Issue 17, 11 September 2026.Rolling‐enabled transfer printing introduces mechanical orientation as a new degree of freedom for heterogeneous silicon photonics. A conventional TE‐like photonic‐crystal nanobeam laser is mechanically rotated by 90° to selectively couple with the TM‐like mode of a silicon waveguide, enabling polarization‐diverse functionality without redesigning the ...

Nanophotonics, Volume 15, Issue 17, 11 September 2026.STEM‐EELS and full‐wave FDTD reveal electron‐driven surface‐polariton modes at buried Au/oxide/Si interfaces with 10 nm SiO2 or Al2O3 spacers. Extinction is dominated by non‐radiative absorption, while oxide permittivity shifts the resonance and controls evanescent‐field penetration across the spacer into silicon.

Ultrafast Optical Hydrogen Modulator in a Palladium Hydride Nanoparticulate Thin Film
Nanophotonics, Volume 15, Issue 17, 11 September 2026.An all‐optical palladium metal‐hydride modulator was investigated with ultrashort laser pulses, which can manipulate hydrogen positions on the femto‐to picosecond timescale. The incident photons activate interstitial hydrogen atoms and their subsequent trajectories affect the dielectric properties of the palladium hydride thin film, providing optical ...

Probing Strong Coupling in Core–Shell Nanoparticles With Fast Electron Beams
physica status solidi (a), Volume 223, Issue 17, 9 September 2026.An exact analytic formalism for evaluating electron‐energy loss and cathodoluminescence probabilities for core–shell nanoparticles explored by electron‐beam spectroscopies is derived. The formalism is exploited to understand strong exciton–plasmon and exciton–Mie mode coupling in nanophotonic architectures.
