Ultra-Low-Loss Hollow-Core Bragg Antiresonant Fiber With Super Bandwidth Transmission Window

IEEE Photonics Journal, 2022
A novel hollow-core antiresonant fiber with a Bragg structure is proposed. It is numerically simulated using a commercial finite element method, and optical properties of the fiber, such as mode field, confinement loss, and bend loss, are numerically ...

Low spontaneous Brillouin scattering in anti-resonant hollow-core fibers in GHz frequency range [PDF]

APL Photonics
Brillouin light scattering (BLS) is a powerful experimental tool that can be used to gain insights into the fundamental and applied properties of matter, like dispersions of quasiparticles in a solid, as well as their spatiotemporal dynamics.

Ultra-low Brillouin scattering in anti-resonant hollow-core fibers

APL Photonics, 2020
Sensitive optical experiments in fiber, including for applications in communications and quantum information, are limited by the noise generated when light scatters from thermally excited guided-acoustic phonons.

Hollow-core photonic band gap fibers for particle acceleration

Physical Review Special Topics. Accelerators and Beams, 2011
Photonic band gap (PBG) dielectric fibers with hollow cores are being studied both theoretically and experimentally for use as laser driven accelerator structures. The hollow core functions as both a longitudinal waveguide for the transverse-magnetic (TM)

Kagome Hollow Core Fiber-Based Mid-Infrared Dispersion Spectroscopy of Methane at Sub-ppm Levels

Sensors, 2019
In this paper, we demonstrate the laser-based gas sensing of methane near 3.3 µm inside hollow-core photonic crystal fibers. We exploit a novel anti-resonant Kagome-type hollow-core fiber with a large core diameter (more than 100 µm) which ...

Hollow core optical fibres with comparable attenuation to silica fibres between 600 and 1100 nm

Nature Communications, 2020
Hollow core fibers have low light attenuation because the light travels through air rather than glass, but other sources of loss have limited the performance so far. Here the authors design and demonstrate a Nested Antiresonant Nodeless hollow core fiber

Simulation of heat transport in textiles inspired by polar bear fur

AIP Advances
The polar bear and several other Arctic mammals use fur composed of hollow-core fibers to survive in extremely cold environments. Here, we use finite element analysis to elucidate the role that the hollow core plays in regulating thermal transport ...
