HoloSpec: Dispersion‐Based 4D Computational Holographic Hyperspectral Imaging

Laser &Photonics Reviews, EarlyView.
HoloSpec, a compact dispersion‐based computational holographic system, achieves four‐dimensional imaging by retrieving 3D spatial structure and high‐resolution spectra from only two monochromatic snapshots. Using a single prism and a monochrome sensor, it resolves 430 spectral channels with 3 nm experimental resolution and 30 μm$\mathrm{\mu}\mathrm{m}$

Micro‐ and Nanopatterning of Highly Conductive PEDOT Thin Films

Macromolecular Rapid Communications, EarlyView.
This work presents micro‐ and nanoscale fabrication strategies for organic thin‐film devices using non‐commercial PEDOT synthesized by V2O5‐mediated oxidative polymerization. Optimized films show controlled thickness and tunable conductivity. At the nanoscale, nanosphere lithography enables large‐area hexagonally packed PEDOT nanopillar arrays down to ...

End‐to‐End Deep Learning Framework for Freeform Metasurfaces via Non‐Uniform Rational B‐Splines Meta‐Atoms

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This work presents a NURBS‐enabled metasurface design framework that combines freeform meta‐atom parameterization with Transformer‐based deep learning. The unified mathematical representation expands geometric degrees of freedom while enabling efficient optical‐response prediction and inverse design.

Decoupling Backward Scattering Control and Forward Beamformed Communication in a Shared‐Aperture Retro‐Reflective/Transmissive Metasurface

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Conceptual illustration of the retro‐reflective and transmissive metasurface (RRTM). The blue radar establishes communication with the UAV via the transmissive mode, whereas the purple surveillance radar acquires the status of friendly units through the retro‐reflective mode and the two modes operate simultaneously within the same decoupled aperture ...

Ultra‐Broadband Optical Characterization of TiO2 Nanotube Arrays Revealing Annealing‐Tunable THz Absorption

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.

Programmable topological metasurface to modulate spatial and surface waves in real time

Nanophotonics
We propose a programmable topological metasurface to integrate intelligent modulations of spatial and surface waves. A general design method is presented to design the programmable metasurface elements with PIN diodes. The surface waves can be controlled

Broadband Electromagnetic Field Prediction at Unseen Wavelengths via Physics‐Guided Neural Operators

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A physics‐guided neural operator is trained on electromagnetic field distributions at discrete wavelengths across diverse nanophotonic structures. At inference, given any permittivity map and query wavelength, the model predicts continuous broadband electric‐field distributions with full‐wave accuracy, including wavelengths unseen during training ...

Compact Snapshot Hyperspectral Imaging With Neural Dispersion‐Engineered Metalens

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A dispersion‐engineered metalens, designed via an end‐to‐end deep learning framework, encodes spectral information through wavelength‐dependent PSF shifts. Fabricated by two‐photon grayscale lithography, the ultrathin device demonstrates outstanding spatial‐spectral reconstruction in both indoor and outdoor scenes, positioning it as a promising ...

Carrier Funneling and Luminescent Collimation for Extreme Diffuse Light Concentration

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Luminescent concentrators show performance millions of times below their thermodynamic limit because of their inefficient design. Carrier funneling combined with luminescent collimation decouples concentration from propagation distance, breaking the practical limitation of current approaches.

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...
