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 ...

Terahertz Metasurface for Spatial Detection of Full Stokes Parameters and Polarization Imaging

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This work presents a THz polarization analyzer with significantly improved robustness against nonuniformity. By integrating four polarization‐sensitive meta‐atoms into a meta‐cell, the metalens splits incident light into six polarization components and generates off‐axis focal spots.

Mode and Polarization Division Multiplexing Based on Chalcogenide‐Glass‐on‐Thin‐Film Lithium Niobate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
High‐index GeSbSe chalcogenide glass loaded on thin‐film lithium niobate enables compact broadband mode‐ and polarization‐division multiplexing. Exploiting direction‐dependent birefringence of x‐cut LNOI, a four‐channel mode (de)multiplexer and asymmetric directional coupler‐based polarization splitter–rotator are demonstrated with great performance in

A Long‐Period Grating Formed by Residual Stress on Thin‐Film Lithium Niobate With Efficient Electro‐Optic and Thermo‐Optic Tuning

Nanophotonics, Volume 15, Issue 9, -Not available-.
Three‐dimensional schematic (a) of the proposed long‐period grating (LPG) on thin‐film lithium niobate (TFLN) and its cross‐sectional view (b) showing a TFLN core with a BCB cladding and a periodic metal structure. Residual stress generated at the metal–BCB interface creates the LPG.

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...
