Reducing loss in practical single ring antiresonant hollow core fibres
Reducing loss in practical single ring antiresonant hollow core fibres
Fibres that guide light in a large hollow core and in a single spatial mode are becoming increasingly important in the delivery of multi-MW peak power beams and to exploit nonlinear dynamics in gases. For high peak power beam delivery a large air core can prevent fibre damage and catastrophic self-focusing effects. Current hollow core fibre (HCF) types include photonic band gap (PBG) and Kagome fibres which rely on a periodically structured and therefore complex and extended cladding [1,2]. A simplified HCF fibre with a single antiresonant glass ring around the core and low loss at yellow wavelengths was recently reported [3]. Here we present an improved fibre design with a lower minimum loss (below 1dB/m) in the near infrared. Stable drawing conditions allow the repeatable fabrication of long lengths of fibre.

Abstract
Fibres that guide light in a large hollow core and in a single spatial mode are becoming increasingly important in the delivery of multi-MW peak power beams and to exploit nonlinear dynamics in gases. For high peak power beam delivery a large air core can prevent fibre damage and catastrophic self-focusing effects. Current hollow core fibre (HCF) types include photonic band gap (PBG) and Kagome fibres which rely on a periodically structured and therefore complex and extended cladding [1,2]. A simplified HCF fibre with a single antiresonant glass ring around the core and low loss at yellow wavelengths was recently reported [3]. Here we present an improved fibre design with a lower minimum loss (below 1dB/m) in the near infrared. Stable drawing conditions allow the repeatable fabrication of long lengths of fibre.
