Micromachining structured optical fibers using focused ion beam milling
C. Martelli, P. Olivero, J. Canning +3
A focused ion beam is used to mill side holes in air-silica structured fibres. By way of example, side holes are introduced in two types of air-structured fibres (1) a photonic cry…
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.
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…
Room temperature self-assembly of mixed nanoparticles into complex material systems and devices
Masood Naqshbandi, John Canning, Brant C. Gibson +1
The ability to manufacture nanomaterials with complex and structured composition using otherwise incompatible materials increasingly underpins the next generation of technologies.…
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…
