Reducing loss in practical single ring antiresonant hollow core fibres

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.
