Loading Dynamics of Cold Atoms into a Hollow-Core Photonic Crystal Fiber

open access: yesFibers, 2020
Cold atoms trapped and guided in hollow-core photonic crystal fibers provide a scalable diffraction-free setting for atom–light interactions for quantum technologies.

Theoretical analysis of backscattering in hollow-core antiresonant fibers

open access: yesAPL Photonics, 2021
We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with gases,

Design of 2 μm Low-Loss Hollow-Core Anti-Resonant Fibers

open access: yesMicromachines, 2023
We systematically studied several of the most traditional hollow-core anti-resonant fiber (HC-ARF) structures, with the aim of achieving low confinement loss, single-mode performance, and high insensitivity to bending in the 2 µm band.

Hollow core fibers for optical amplification [PDF]

open access: yesOptics 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 ...

Geometrical Scaling of Antiresonant Hollow-Core Fibers for Mid-Infrared Beam Delivery

open access: yesCrystals, 2021
We numerically investigate the effect of scaling two key structural parameters in antiresonant hollow-core fibers—dielectric wall thickness of the cladding elements and core size—in view of low-loss mid-infrared beam delivery.

Optimising the performances of hollow antiresonant fibres [PDF]

open access: yes, 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 ...

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

open access: yesNature 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

Dispersion in a Gas Filled Hollow Core Photonic Crystal Fiber

open access: yesمجلة بغداد للعلوم, 2014
Hollow core photonic bandgap fibers provide a new geometry for the realization and enhancement of many nonlinear optical effects. Such fibers offer novel guidance and dispersion properties that provide an advantage over conventional fibers for various ...
