Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

One‐Step Fabrication of Non‐Ablative Microstructures for Efficient Second Harmonic Generation on LiNbO3 Thin Film

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This study presents a novel one‐step femtosecond laser modification technique for fabricating high‐quality periodic metasurfaces on lithium niobate thin films without surface damage and scattering centers. Under oblique incidence at 1030 nm, a 4.75‐fold enhancement in second‐harmonic generation efficiency is achieved through complementary mechanisms ...

Disorder‐Enabled Directional Delocalization and Wave Steering in Time‐Modulated Dirac Materials

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Random temporal modulation of a vector potential in a Dirac medium produces disorder‐enabled directional delocalization: waves propagating parallel to the modulation direction remain perfectly delocalized, whereas those in all other directions undergo strong Anderson localization. Temporal disorder thus acts as a directional filter, enabling collimated
