Sol-gel processing to form doped sol-gel monoliths inside hollow core optical fiber and sol-gel core fiber devices made thereby [PDF]

, 2002
A process of fabricating a fiber device includes providing a hollow core fiber, and forming a sol-gel material inside the hollow core fiber. The hollow core fiber is preferably an optical fiber, and the sol-gel material is doped with a dopant.

Release oscillation in a hollow fiber – Part 1: Mathematical model and fast estimation of its frequency

Journal of Low Frequency Noise, Vibration and Active Control, 2019
This paper studies a micro/nano scale capillary flow in a hollow fiber and its oscillation. The hollow fiber is immersed into a liquid (e.g. water), and the isolated air in the fiber plays as a spring-like oscillation. An oscillation model is established

Long-lived refractive index changes induced by femtosecond ionization in gas-filled single-ring photonic crystal fibers

, 2018
We investigate refractive index changes caused by femtosecond photoionization in a gas-filled hollow-core photonic crystal fiber. Using spatially-resolved interferometric side-probing, we find that these changes live for tens of microseconds after the ...

Taming the Immiscibility of Gold, Iron, and Boron to Craft Chemodegradable Nanoparticles for Multimodal Imaging and Radiotherapy

Advanced Healthcare Materials, EarlyView.
Over half of cancer patients undergo radiotherapy. Laser ablation enabled the synthesis of immiscible Au‐Fe‐B nanoparticles designed as degradable bimodal radiosensitizers for X‐ray radiotherapy (XRT), boron neutron capture therapy (BNCT), and bimodal imaging for X‐ray computed tomography (CT) and magnetic resonance imaging (MRI). These nanosensitizers
