Air-structured optical fibre drawn from a 3D-printed preform
Kevin Cook, John Canning, Sergio Leon-Saval +5
A structured optical fibre is drawn from a 3D-printed structured preform. Preforms containing a single ring of holes around the core are fabricated using filament made from a modif…
Step-index optical fibre drawn from 3D printed preforms
Kevin CooK, Geoffrey Balle, John Canning +7
Optical fibre is drawn from a dual-head 3D printer fabricated preform made of two optically transparent plastics with a high index core (NA ~ 0.25, V > 60). The asymmetry observed…
Nanoscale changes with low temperature annealing inside composite optical fibres
Wen Liu, John Canning, Kevin Cook +1
Nanoscale glass milling with mild thermal annealing is proposed and shown to occur within a tri-material composite W profile optical fibre.
Large dynamic range SPR measurements in the visible using a ZnSe prism
John Canning, Jing Qian, Kevin Cook
Large dynamic index measurement range (n = 1 to n = 1.7) using surface plasmon resonance (SPR) shifts is demonstrated with a ZnSe prism at 632.8 nm, limited by the available high i…
Percolation diffusion into self-assembled mesoporous silica microfibres
John Canning, George Huyang, Miles Ma +7
Percolation diffusion into long (11.5 cm) self-assembled, ordered mesoporous microfibres is studied using optical transmission and laser ablation inductive coupled mass spectrometr…
The viscosity of silica fibres
Li-Yang Shao, John Canning, Tao Wang +2
The viscosity of an optical fibre over 1000 to 1150 °C is studied by inscribing an optical fibre Bragg grating that can withstand temperatures up to 1200 °C and monitoring fibre el…
Temperature and strain characterization of regenerated gratings
Tao Wan, Li-Yang Shao, John Canning +1
Both temperature and strain characterization of seed and regenerated gratings with and without post-annealing is reported. The high temperature regeneration has significant impact…
Tailoring surface interactions, contact angles, drop topologies and self-assembly using laser irradiation
John Canning, Hadrien Weil, Masood Naqshbandi +2
UV laser irradiation (lambda = 193 nm), below and above damage thresholds, is used to both alter and pattern the surface properties of borosilicate slides to tune and control the c…
New theory of femtosecond induced changes and nanopore formation
John Canning, Matthieu Lancry, Kevin Cook +1
Recent results confirm the presence of molecular oxygen proving that recombination of dissociated silica bonds does not occur. This combined with the observation of nanopores withi…
