Theoretical analysis of backscattering in hollow-core antiresonant fibers
APL 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
Micromachines, 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.

Anti-resonance, inhibited coupling and mode transition in depressed core fibers [PDF]
, 2020 The depressed core fiber (DCF), consisting of a low-index solid core, a high-index cladding and air surrounding, is in effect a bridge between the conventional step-index fiber and the tube-type hollow-core fiber from the point of view of the index ...

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

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 ...

Robust low loss splicing of hollow core photonic bandgap fiber to itself [PDF]
, 2013 Robust, low loss (0.16dB) splicing of hollow core photonic band gap fiber to itself is presented. Modal content is negligibly affected by splicing, enabling penalty-free 40Gbit/s data transmission over > 200m of spliced ...

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

Fiber transport of spatially entangled photons [PDF]
, 2011 Entanglement in the spatial degrees of freedom of photons is an interesting resource for quantum information. For practical distribution of such entangled photons it is desireable to use an optical fiber, which in this case has to support multiple ...
