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…
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…
Intelligent smartphone-based portable network diagnostics for water security Case Study realtime pH mapping of tap water
Arafat Hossain, John Canning, Sandra Ast +2
Using a field-portable, smartphone fluorometer to assess water quality based on the pH response of a designer probe, a map of pH of public tap water sites has been obtained. A cust…
