Intrinsically Design‐Rule‐Compliant Nanophotonic Inverse Design via Learned Generative Manifolds
Laser &Photonics Reviews, EarlyView.A generative reparameterization framework for nanophotonic inverse design is introduced, restricting optimization to a learned manifold of design‐rule‐compliant geometries. Unlike conventional penalty‐based approaches, fabrication constraints are encoded intrinsically within the design representation.

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices
Laser &Photonics Reviews, EarlyView.ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Laser &Photonics Reviews, EarlyView.A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic

Laser &Photonics Reviews, EarlyView.Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

Fourier imaging for nanophotonics
NanophotonicsAbstract Standard optical characterization and spectroscopy techniques rely on the measurement of specular reflection, transmission, or emission at normal incidence. Although the usefulness of these methods is without question, they do not provide information on the angular dependence of the scattered light and, therefore, miss ...

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.

Laser &Photonics Reviews, EarlyView.A dual‐gated nanophotonic platform integrates lanthanide‐doped upconversion nanoparticles with a stimuli‐responsive silk–zirconia photonic crystal to enable multilevel optical encryption. Resonant photonic coupling allows hydration‐dependent modulation of visible emission under near‐infrared excitation, achieving reversible switching between decoy and ...

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 ...

Photonic nanovoids for tailored optoelectronic response in silicon solar cells
Responsive Materials, EarlyView.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.
