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.

Photonic nanovoids for tailored optoelectronic response in silicon solar cells
Optoelectronic workflow followed by experimental validation, demonstrating state‐of‐the‐art efficiency gains. Abstract As crystalline silicon (c‐Si) solar cells become thinner to reduce cost and weight, the optical design principles that govern light trapping (LT) must evolve.

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.

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.

Inverse Drexhage Effect in Epsilon‐Near‐Zero Substrates
Radiative emission of dipoles near substrates is shown to reverse between (a) perfect electric conductors and (b) epsilon‐near‐zero (ENZ) media. The schematic highlights switch from vertical to horizontal dipole dominance, governed by interference with image dipoles, leading to directional emission into the upper half‐space and enabling new strategies ...
