Low Spontaneous Brillouin Scattering in Anti-Resonant Hollow-Core Fibers in GHz Frequency Range
Ryan E. Dunagin, Robbie Mears, Dario Bueno-Baques +6
Brillouin light scattering (BLS) is a powerful experimental tool that can be used to get insights into the fundamental and applied properties of matter, like dispersions of quasipa…
Tunable megawatt-scale sub-20 fs visible pulses from a fiber laser source
Mohammed Sabbah, Robbie Mears, Leah R. Murphy +4
Ultrafast laser pulses that are both tunable in wavelength and very short in duration are essential tools in fields ranging from biomedical imaging to ultrafast spectroscopy. While…
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…
