Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies
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 dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

A Self‐Evolving Agentic Framework for Metasurface Inverse Design
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 ...

Compact Single‐Shot Incoherent Edge Detection With a Polarization‐Multiplexed Metalens
A polarization‐sensitive metalens enables single‐shot incoherent edge detection by generating two polarization‐dependent images and digitally subtracting them to realize a high‐pass optical transfer function. ABSTRACT Edge detection under incoherent illumination is highly desirable for compact vision systems but remains challenging due to the lack of ...

Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Transmission‐Mode Silicon‐Rich Nitride Mie‐Void Metasurfaces in the Visible
Transmission‐mode Mie‐void metasurfaces are demonstrated in silicon‐rich nitride, where localized void resonances hybridize with slab‐guided and Fabry–Pérot‐like modes in a finite film, producing a quantified avoided crossing between coupled modes. Controlled void depth tunes the visible transmission spectrum, enabling structural color and spatial ...

Oblique metallization creates one‐sided opaque metagratings that route zero‐order‐hidden optical power between nonzero diffraction and material dissipation. Cross‐sectional‐SEM‐guided models reproduce measured zero‐order spectra and reveal direction‐selective channel exchange governed by morphology and Rayleigh‐order availability.
