A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

Advanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced

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

Advanced 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

Advanced 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 ...

Seven‐Fold Compression of Mid‐Infrared Pulses Using a Series of Titanium Dioxide Plates

Advanced Optical Materials, EarlyView.
Here, a sequence of three titanium dioxide plates is used to compress a mid‐infrared pulse from 103.9 femtoseconds to 14.1 femtoseconds (about two optical cycles) without the use of external dispersion compensation. The approach maintains high efficiency and produces pulses with a stable carrier‐envelope phase, providing a compact platform for ...

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2

Advanced Optical Materials, EarlyView.
Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.
