Etch‐Less Nanostructures for Photoluminescence Modification From Plasma‐Enhanced Chemical Vapor Deposition‐Grown Silicon Nanocrystals

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
The luminescence from Si‐nanocrystals embedded in a waveguide layer is strongly modified by a shallow photo resist grating on top, which is fabricated by large area laser interference lithography. Guided mode resonances and quasi bound states in the continuum lead to increased upward coupling of radiation, which are also used to experimentally map the ...

Geometry‐Controlled Assembly of Self‐Standing Nanorods With Undisturbed Plasmonics

Advanced Science, Volume 13, Issue 45, 13 August 2026.
This study reports a geometry‐driven assembly strategy to vertically align Au@Ag core–shell nanorods on PS beads. This well‐defined architecture enables the preservation of the intrinsic optical response of individual nanorods. Thus, demonstrate a highly reproducible SERS enhancement with exceptional uniformity.

Engineering Disordered Many‐Particle Plasmonic Nanoclusters for Wafer‐Scale Uniform and Giant Electromagnetic Field Enhancement

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
This work presents a lithography‐ and etching‐free dewetting strategy that assembles many‐particle gold nanostructures into uniform plasmonic substrates at the wafer scale. By forming satellite nanoparticles between larger ones, the method achieves giant and highly reproducible electromagnetic enhancement.

Enhanced Enantioselective Optical Trapping Enabled by Longitudinal Mie Resonances in Silicon Nanodisks

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Longitudinal Mie resonances in silicon nanodisks, excited by an azimuthally–radially polarized beam, generate strong optical chirality gradients with minimal achiral background. Magnetic quadrupole modes enable selective enantiomer trapping, achieving predicted selectivities over 100 for |κ|≥0.03 $\vert \kappa \vert \ge 0.03$ and robust performance ...

Increasing of Q Factor of Quasi‐Bound States in the Continuum With Increased Asymmetry Parameter in a Silicon Metasurface Array

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Quasi‐bound states in the continuum (qBICs) can support resonances with high quality (Q) factor. Traditionally, maintaining a high Q factor requires a small α, which brings significant challenges for nanofabrication. In contrast, our study finds an increase in the Q factor with increasing of α in a metasurface array composed of Si blocks with circular ...

Third Harmonic Generation in Transparent Longitudinal Epsilon‐Near‐Zero Multilayers

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Transparent longitudinal epsilon‐near‐zero stacks enable field‐enhanced nonlinear light generation while preserving high near‐infrared pump transmission. Broadband third‐harmonic generation is experimentally observed demonstrating that TLENZ architectures can mitigate pump‐loss limitations and offer a promising platform for transparent nonlinear ...

Suppressing Stitching Errors in Full‐Sensor‐Plane Color Routers via Optical Structural Similarity

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Angle‐specific nanophotonic color routers are assembled from a library of inverse‐designed unit cells matched to local incidence angles. Optical structural similarity (OSS) constrains neighboring permittivity profiles during optimization, suppressing inter‐cell stitching errors without additional full‐wave simulations and enabling oblique‐incidence ...
