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…
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…
Near orthogonal launch of SPR modes in Au films
John Canning, Akib Karim, Nikki Tzoumis +3
We report the excitation of a surface plasmon resonance (SPR) close to the orthogonal axis of a gold (Au) film on borosilicate glass. Direct spectroscopic measurement of SPR shifts…
Lab-in-a-phone: Smartphone-based Portable Fluorometer for pH Field Measurements of Environmental Water
Md. Arafat Hossain, John Canning, Sandra Ast +3
A novel portable fluorometer combining the attributes of a smartphone with an easy fit, simple and compact sample chamber fabricated using 3D printing has been developed for pH mea…
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…
