Plasmon–Exciton Coupling Enhances Second‐Order Nonlinear Response in Borophene–ZnO Hybrid Structures

Laser &Photonics Reviews, EarlyView.
Nonlinear interactions between plasmons in borophene and excitons in ZnO lead to enhanced nonlinear and incoherent cathodoluminescence, as well as coherent second harmonic generation, under electron‐beam and laser irradiations, respectively. The anisotropic response of borophene, revealed as in‐plane hyperbolic polariton propagation, acts as a control ...

Supercontinuum generation in 1-decanol

Optics Express
Although solids have been recently used in ultrafast experiments for spectral broadening due to their relatively high nonlinearity, their sensitivity to damage limits their long-term stability. Liquids are a possible alternative to solids as a nonlinear medium because of their comparable nonlinearity and resistance to permanent ...

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Active Hyperspectral Sensor Based on MEMS Fabry-Pérot Interferometer

Sensors, 2019
An active hyperspectral sensor (AHS) was developed for target detection and classification applications. AHS measures light scattered from a target, illuminated by a broadband near-infrared supercontinuum (SC) light source.

Photochemical fluorescence activation in arrays of microspherical containers

Responsive Materials, EarlyView.
Photoresponsive microdroplets can be produced with precise structural control from organic solutions of a photoactivatable fluorophore and aqueous solutions of a surfactant at a microfluidic cross junction. These dye‐doped microspheres assemble spontaneously in close‐packed arrays in aqueous media.

Laser‐Synthesized Carbon‐Coated Elemental Bismuth Nanoparticles for Sustained Reactive Oxygen Species Generation Under Visible‐Light Irradiation

Small, EarlyView.
Femtosecond laser ablation of bismuth in acetone yields carbon‐coated nanoparticles with a metallic Bi0 core and an amorphous carbon shell. The core‐shell architecture preserves visible‐light‐driven redox activity and enables sustained hydroxyl‐radical generation.

Engineering Carbon Nanotube Quantum Well Defects With Recognition Tripeptides for Optical Detection of Extracellular Vesicles in Plasma

Small, EarlyView.
A three‐residue peptide bioconjugated onto a carbon nanotube quantum defect turns the near‐infrared emission of quantum defects into a reporter of integrins on intact extracellular vesicles, directly in human plasma. The sensor reveals that healthy fibroblast vesicles carry as much RGD‐binding integrin as cancer‐derived ones, an adhesion‐associated ...
