Review on All-Fiber Online Raman Sensor with Hollow Core Microstructured Optical Fiber

Photonics, 2022
Raman spectroscopy is widely used for qualitative and quantitative analysis of trace components in scientific fields such as food safety monitoring, drug testing, environmental monitoring, etc. In addition to its demonstrated advantages of fast response,

Hollow core fibers for optical amplification [PDF]

Optics Letters, 2019
Hollow core optical fibers are normally passive light transport components. In contrast, within this Letter, we numerically investigate the possibility of using them as optical amplifiers, through the adoption of a novel fiber structure. We show that optical amplification can be achieved in hollow core fibers, where the cladding region is partially ...

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 ...

Optimising the performances of hollow antiresonant fibres [PDF]

, 2011
We study the loss of novel antiresonant hollow-core fibres, demonstrate the existence of a wavelength independent optimum distance between core-surround and solid outer cladding, and provide useful guidelines for the fabrication of practical low-loss ...

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.
