About this position

PhD opportunity at the University of Southampton in Spatiotemporal Control of Ultrafast Multimode Fibre Amplifiers.

This project sits in the Faculty of Engineering and Physical Sciences and is supervised by Dr Lin Xu and Dr Duanyang Xu. The research focuses on ultrafast fibre lasers, multimode fibre amplifiers, spatiotemporal control, nonlinear optics, and optical physics. The aim is to develop innovative multimode fibre amplifiers that can generate high-energy, ultrashort pulses with tailored beam profiles by combining adaptive amplitude and phase shaping with nonlinear amplification.

The project will investigate modal interactions, intermodal dispersion, gain distribution, and nonlinear propagation in multimode fibres. It combines numerical modelling with experimental validation to understand how engineered input fields can preserve temporal integrity while shaping the spatial profile of amplified pulses. Potential applications include high-energy ultrafast laser systems, nonlinear microscopy, precision material processing, advanced imaging, spectroscopy, and optical manipulation.

Eligibility: applicants should hold a UK 2:1 honours degree or an international equivalent. An English language qualification is required if applicable. The opportunity is advertised as a competition-funded PhD project for students worldwide.

Funding: the page mentions Horizon Europe fee waivers, University Presidential Bursaries, and school studentships that may cover tuition and provide a stipend for living costs, with funding awarded on a rolling basis.

How to apply: submit an online application for Research study in the 2027/28 cycle, Faculty of Engineering and Physical Sciences, and search for programme PhD ORC (7097). Add the supervisor’s name in section 2 and include a CV, two academic references, transcripts/certificates, and English language evidence if needed.
