Nanomaterial‐Incorporated Nonlinear Optical Waveguides Explored With All‐Fiber Multiphoton Polymerization

open access: yesAdvanced Optical Materials, EarlyView.
Nonlinear waveguides are fabricated via an all‐fiber‐based multiphoton polymerization approach incorporating upconversion nanoparticles (UCNPs), which enable both multiphoton absorption at telecommunication wavelengths and nonlinear saturable absorption operation.

Localized Ion Irradiation Enables Topography‐Free High‐Tc Superconducting Metamaterials

open access: yesAdvanced Optical Materials, EarlyView.
A topography‐free oxygen ion‐irradiation strategy is demonstrated for patterning superconducting YBCO terahertz metamaterials without physical material removal. The approach preserves film integrity while enabling large spectral tunability, ultrafast optical modulation, and dual‐band resonance control, providing a scalable platform for low‐loss ...
