Direct and inverse design of microstructured optical fibres
Microstructured optical fibres, where an arrangement of air holes running longitudinally along the fibre guides light in either a solid or a hollow core, have created new opportunities in diverse areas of science and technology. Applications range from the generation of supercontinuum light to …

Deposition of electronic and plasmonic materials inside microstructured optical fibres
Optical fibres are the transport medium of today's digital information. Nowadays, modern optical telecommunication systems make use of semiconductor optoelectronic devices to generate, control and detect light. The union of the two technologies, namely fibre photonics and semiconductor electronics …

A theoretical study into the fundamental design limits of devices based on one-and two-dimensional structured fibres
… of the latest key technologies used to produce optical fibre devices for telecommunication system applications. The first technology (fibre Bragg gratings) concerns the 1-dimensional perturbation of the refractive index of an optical fibre (i.e. along the propagation axis of the fibre), whereas …

Optical fibre-based minimally-invasive blood glucose monitoring system.
… an alternative solution. This thesis shows that optical fibre can act both as a sensing element and a medium to carry information in real time. Optical methods are useful as they require a very small sample volume (< 1 μL) and are also capable of remote probing. An investigation into various …

Mathematical Modelling of Fibre Fabrication; Coupling Heat Transport with Fluid Flow in Extrusion
We consider microstructured optical fibre fabrication by a two-step process: preform extrusion and fibre drawing. During preform extrusion a molten glass bulk billet is pushed through a die to give a preform, the macroscopic version of the fibre, which is stretched either by pulling with a given …

Fabrication and applications of lead-silicate glass holey fibre for 1-1.5 microns: nonlinearity and dispersion trade offs
This thesis describes the development of novel microstructured optical fibres (MOFs), namely holey optical fibres (HFs), based on a commercial highly nonlinear non-silica glass: lead silicate glass, for their specific incorporation in optical devices based on fibre nonlinearity and dispersive …

High Resolution Distributed Sensing Using Exposed-Core Fibres
… for civil infrastructure monitoring. Based on optical frequency domain reflectometry (OFDR), this thesis extends distributed sensing to biomedical applications, with a focus on the detection of small particles. A high-resolution distributed sensing method has been proposed, in which an …
