Mechanical stresses in holey fibres. The development of holey fibres constitutes arguably the most exciting development in fibre optics in recent years. We will analyze the mechanical stresses in these fibres, which, together with the optical calculations and associated experiments, will allow us to design novel fibre-based devices. This will allow Nufern to develop new products based on holey fibres.
Novel multi-channel and nonlinear Bragg grating devices. High capacity and reliable telecommunications links are essential for many aspects of modern life and work. Optical fibres offer essentially unlimited capacity, but their optimal use requires the transmission of multiple wavelength channels simultaneously. This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. ....Novel multi-channel and nonlinear Bragg grating devices.

3. To develop an in-vivo optical fibre probe for monitoring and quantifying the changes of mineralised carious tissue during remineralisation.
This project will enable patients prone to orthodontic induced root resorption to be identified and also to assist with validating repair of enamel tooth structure in a non-surgical manner. It is anticipated to result in the development of a novel fibre optic instrument with applications beyond dentistry.

Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre. Current optical fibre networks use only a fraction of their capacity. This is in part because optical amplifiers with enough bandwidth do not exist. However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric ampli ....Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre.

However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric amplifier with a world record bandwidth, which will enable the full capacity of optical fibre to be exploited.Read moreRead less

Improving the sensitivity and availability of in-vitro immuno-diagnostic tests is a critical goal towards developing real time efficient tools for the detection of infectious diseases, cancers, allergies and auto-immune diseases. The goal is to increase the sensitivity of these tests by reducing background noise that has been a feature of the commonly used ELISA technology. This will be achieved by developing a novel optical integrated waveguide array supporting a large range of distributed tests, including several based on a novel multi-colour detection scheme. This massively parallel approach will underpin a new generation of low-cost, efficient diagnostic tests.Read moreRead less
