About the project

This project will exploit computer simulations to investigate the dynamics of the generation of light in such large, few-mode or multimode, optical fibres. 

As fibre lasers get more and more powerful, the fibre core size must increase to minimise optical nonlinearities and avoid material damage. This adds spatial degrees of freedom to the laser beam that have to be controlled in order to obtain a clean, well-behaved laser output. 

We will analyse the dynamics of the spatial light profile and its dependence on the gain medium, fibre losses, optical nonlinearities, chromatic dispersion, and thermal and acoustic effects. These numerical and theoretical investigations will be performed in close collaboration with corresponding high-power laser experiments in our labs and at our industrial partners.

You will join our vibrant team of students, postdocs, and senior researchers developing the next generation of high-power fibre lasers. Specifically, on this project you will work on the theory and numerical simulation of the fundamental processes that currently limit the maximum output power of fibre lasers.

If you have an interest in computational physics and research in the exciting area of high-power lasers, you would be highly suitable for this project. You will benefit from our world-leading expertise in these fields and exploit state-of-the-art computer hardware for your research on a PhD project which is highly relevant for the future development of the next generation of fibre lasers and their applications in, for example, advanced digital manufacturing and medical surgery.  

The project is part of a major initiative funded by the UK Research and Innovation Council at the Optoelectronics Research Centre, University of Southampton, that combines new fibre technology with state-of-the-art control mechanisms, including machine learning, to reach unprecedented laser powers with full control over the beam shape.

The Optoelectronics Research Centre is committed to promoting equality, diversity, and inclusivity, as demonstrated by the school’s Athena Swan award. We welcome all applicants regardless of their gender, ethnicity, disability, sexual orientation or age. We take personal circumstances into account, and will give full consideration to applicants seeking to study part time. The campus has onsite childcare facilities.
