Conversion of Spin‐Orbit‐Coupled Optical Vortices via Complex Coupling

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
A four‐step Floquet protocol in a straight terahertz waveguide array uses metallic separators to selectively control interwaveguide coupling. The resulting angular‐momentum‐dependent coupling enables Floquet engineering of OAM states, giving rise to corner states, conversion between opposite total‐angular‐momentum states, and edge states.

Arbitrary Wavefront Manipulation in Real Space and Momentum Space Based on Elliptical Structures

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Leveraging elliptical structures—while preserving real space arbitrary wavefront manipulation—we generalize the manipulation to momentum space rather than only sustaining topological singularities. Multifunctional integrated outputs, such as beam deflection and focusing, can be flexibly achieved in the near–infrared communication band, and the ...

Deep Reinforcement Learning Inverse Design of Dielectric Metasurfaces Supporting Dual Quasi‐BIC Resonances

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
A deep reinforcement‐learning framework designs dielectric metasurfaces supporting dual quasi‐BIC resonances under tightly coupled multi‐objective constraints. By combining D3QN, rollout‐based lookahead, reward normalization, and prioritized replay, the method stabilizes the optimization of the resonance wavelength, quality factor, and near‐field ...

Polarization‐Multiplexed Double‐Helix/Airy Metalens for Depth‐Resolved Texture Imaging With Extended Depth‐of‐Field

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
To address the trade‐off between depth discriminability and texture preservation in PSF‐engineered imaging, a polarization‐multiplexed metalens is developed to decouple depth estimation from extended‐depth‐of‐field texture acquisition. The DH‐derived depth guides depth‐matched Airy PSF selection for non‐blind texture recovery, while computational ...

Sparse‐Aperture Quasi‐Achromatic Spintronic Terahertz Emitter Enabled by Binary‐Phase Metasurface and Multi‐Spectral Intensity Optimization

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
We propose a sparse‐aperture shared‐aperture design with multispectral intensity optimization, enabling a Pt/W binary‐phase metasurface directly integrated with a spintronic emitter. The device achieves quasi‐achromatic focusing across 1.0–1.5 THz, with intensity fluctuation below 33% and edge preservation above 0.68.
