Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies

Laser &Photonics Reviews, EarlyView.
We introduce 3D nanoprinting of gold nanoparticle assemblies and show that their broad optical responses remain reproducible despite structural disorder. This robustness is attributed to ensemble‐averaged plasmonic responses from many local coupling regions.

A Self‐Evolving Agentic Framework for Metasurface Inverse Design

Laser &Photonics Reviews, EarlyView.
Turning a target optical response into working inverse‐design code normally demands specialized computational‐electromagnetics and software‐engineering expertise. A self‐evolving agentic framework lowers this barrier: from a natural‐language request, it writes the optimization code that drives a physical solver and improves itself by revising human ...

High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, EarlyView.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators

Small, EarlyView.
The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

Small, EarlyView.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
The physical origins of resonance effects in one‐dimensional periodic photonic lattices are studied to assess the relative roles of Fabry–Perot, Mie, and guided‐mode resonance mechanisms. It is shown that lattice resonance is fundamentally governed by lateral leaky Bloch modes and their coupling to external radiation via guided‐mode resonance.

Band‐Selective, Low‐Dispersion Terahertz Attenuators Based on 3D Bulk Metamaterials Leveraging De‐latticed Cross‐Bar Resonator Ensembles

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This paper presents 3D bulk metamaterials in which diced cross‐bar meta‐grains are randomly dispersed in a polymer matrix by molding. The de‐latticed composite provides isotropic and band‐selective THz attenuation with over tenfold dispersion suppression compared to the periodic metasurface.

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 ...

Large‐Aperture, WFOV Broadband Achromatic Metalens Enabled by Forward Mapping Optimization and Hybrid Algorithmic Framework

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
A novel large aperture metalens design strategy achieves broadband achromatic imaging across the visible spectrum (400–680 nm) with a 100° field of view. By incorporating forward mapping optimization and a hybrid algorithm framework, this approach overcomes the limit between aperture size, field of view, and chromatic aberration correction, providing a
