Nanofilms on a hollow core fiber [PDF]
Optical Engineering, 2006 We experimentally study the behavior of one multimode fiber–hollow core fiber–multimode fiber structure when nanofilms are deposited on it with the aim of developing practical evanescent field-based devices, such as sensors, filters, etc. The electrostatic self-assembly (ESA) method is used as the deposition technique and the chosen polymers are PDDA ...

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.

Birefringent Anti-Resonant Hollow-Core Fiber [PDF]
Journal of Lightwave Technology, 2020 Hollow-core fibers have demonstrated record performance in applications such as high-power pulse delivery, quantum computing, and sensing. However, their routine use is yet to become reality. A major obstacle is the ability to maintain the polarization state of light over a broad range of wavelengths, while also ensuring low attenuation and single-mode

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 ...

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.
