Highly multi-mode anti-resonant hollow core fibres
Robbie Mears, Kerrianne Harrington, William J Wadsworth +2
We report the characterisation of anti-resonant hollow core optical fibres guiding at least 50 spatial modes in the infrared. Their propagation losses were measured to be between 0…
Resonance-free deep ultraviolet to near infrared supercontinuum generation in a hollow-core antiresonant fibre
Mohammed Sabbah, Robbie Mears, Kerrianne Harrington +4
Supercontinuum generation in the ultraviolet spectral region is challenging in solid-core optical fibres due to solarization and photodarkening. Antiresonant hollow-core fibres hav…
Multi-core anti-resonant hollow core fibre
Robbie Mears, Kerrianne Harrington, William J Wadsworth +2
We report the fabrication and characterisation of a multi-core anti-resonant hollow core fibre with low inter-core coupling. The optical losses were 0.03 and 0.08 dB/m at 620 and 1…
Optical absorption spectrum reveals gaseous chlorine in anti-resonant hollow core fibres
Kerrianne Harrington, Robbie Mears, James M. Stone +3
We have observed unexpected spectral attenuation of ultraviolet light in freshly drawn hollow core optical fibres. When the fibre ends are left open to atmosphere, this loss featur…
Guidance of ultraviolet light down to 190 nm in a hollow-core optical fibre
Robbie Mears, Kerrianne Harrington, William J. Wadsworth +3
We report an anti-resonant hollow core fibre with ultraviolet transmission down to 190 nm, covering the entire UV-A, UV-B and much of the UV-C band. Guidance from 190 - 400 nm is a…
