Opto-Electronic Advances, 2023 We report broadband all-fiber optical phase modulation based on the photo-thermal effect in a gas-filled hollow-core fiber. The phase modulation dynamics are studied by multi-physics simulation.

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.

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 ...

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 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

Dispersion in a Gas Filled Hollow Core Photonic Crystal Fiber
مجلة 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 ...

Borosilicate Based Hollow-Core Optical Fibers [PDF]
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 ultrapure silica glass.

Terahertz Hollow Core Antiresonant Fiber with Metamaterial Cladding
Fibers, 2020 A hollow core antiresonant photonic crystal fiber (HC-ARPCF) with metal inclusions is numerically analyzed for transmission of terahertz (THz) waves. The propagation of fundamental and higher order modes are investigated and the results are compared with
