Harnessing Nanoparticles In Glass Optical Fibres

The project will include fabrication of subwavelength elliptical core fibres, which can be shown to have high nonlinear polarisation.

Using the fabricated fibres, their nonlinear polarisation characteristics will be investigated experimentally and compared to those predicted by the model. The field of nonlinear processes in subwavelength waveguides is a new field of research in which our discipline plays a pioneering role.

The drivers for our work include the development of nonlinear fibre-based devices for all-optical data processing, switching and optical limiting. Our recent work on the development of a new theoretical model for nonlinear pulse propagation in highly nonlinear fibres, fabrication of the world’s smallest core optical fibres, and experimental confirmation of our new theoretical model has attracted a lot of attention in the science community.

Within this project, we would like to extend our new nonlinear model to include nonlinear polarisation.
