3D Printed Hollow-Core Terahertz Fibers

Fibers, 2018
This paper reviews the subject of 3D printed hollow-core fibers for the propagation of terahertz (THz) waves. Several hollow and microstructured core fibers have been proposed in the literature as candidates for low-loss terahertz guidance.

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.

Facile Cell-Friendly Hollow-Core Fiber Diffusion-Limited Photofabrication

Frontiers in Bioengineering and Biotechnology, 2021
Bioprinting emerges as a powerful flexible approach for tissue engineering with prospective capability to produce tissue on demand, including biomimetic hollow-core fiber structures. In spite of significance for tissue engineering, hollow-core structures

Analytical Formulas for Dispersion and Effective Area in Hollow-Core Tube Lattice Fibers

Fibers, 2021
In this work, we propose analytical formulas for the estimation of dispersion properties and effective area of the fundamental mode of hollow-core inhibited coupling fibers with a microstructured cladding composed by a ring of dielectric tubes.

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 ...

Borosilicate Based Hollow-Core Optical Fibers

Fibers, 2019
We discuss the fabrication of hollow-core optical fibers made of borosilicate glass. We show that, despite the high attenuation of the glass relative to silica, the fiber optical losses can be of the same order of magnitude of those obtained by using ...
