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.

Dual-core antiresonant hollow core fibers
Optics Express, 2016 In this work, dual-core antiresonant hollow core fibers (AR-HCFs) are numerically demonstrated, based on our knowledge, for the first time. Two fiber structures are proposed. One is a composite of two single-core nested nodeless AR-HCFs, exhibiting low confinement loss and a circular mode profile in each core.

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
