The aim of this project is to develop a broadband and high brightness optical fibre source based on optical supercontinuum generation (i.e. low-coherence optical signals with octave or more bandwidth). Unlike similar sources demonstrated recently which rely on expensive bulk femtosecond pump lasers, this source will be pumped by a large pulse-energy optical fibre laser and use stimulated Raman scattering to seed the continuum generation. The primary outcome will be a compact low-cost all-fibre supercontinuum source with a wide range of applications in areas such as optical metrology, optical coherence tomography, and high resolution non-contact position and motion sensing.Read moreRead less
Ringed photonic crystal fibres for broadband nonlinear optics. The technology developed from this project will enable organic molecules to be detected, identified and quantified.

Structural integrity monitoring, to anticipate and prevent failure, is a multi-billion dollar effort worldwide. Detailed assessment of the capability of fibre Bragg gratings to measure strain profiles along the grating length, i.e. intragrating sensing, and thereby detect structural ?hot spots? before failure is essential for effective systems. They will be used to determine strain gradients similar to those found in common problem areas, such as the tips of elliptic notches and disbonding at the ends of composite joints. Additionally, grating refractive index profiles will be characterised using imaging techniques, to assess performance and possible changes to gratings after prolonged use.Read moreRead less
