PhD Studentship Next Generation of Erbium-doped Optical Fibres and Amplifiers for Telecommunication Applications

Applications are invited for a PhD position in material sciences to join University of Southampton, UK. The initial contract for this position is 5 years. Applications should be sent before January 31, 2020.

We are looking for PhD applicants with a background in physics, material sciences, chemistry, or engineering to work on an industrially funded (Huawei) programme to develop next generation erbium doped fibres and optical amplifiers for high capacity optical communication systems. The successful candidate will be part of a world-leading research team working on fibre fabrication and fibre amplifiers at the Optoelectronics Research Centre (ORC).

The introduction of Er-doped fibre amplifiers (EDFAs), which amplify signals transmitted in the lowest loss window (~1550nm) of silica based single mode fibre, has resulted in a breakthrough in fibre optical transmission systems, increasing the capacity of current commercial global networks to the tens of terabit/s regime. As the demand for higher optical fibre data transmission capacity is increasing, with year-on-year growth of 40%, there is great interest in studying new amplifiers that can overcome the bandwidth limitations of conventional EDFAs. This research project will focus on the development of low-loss erbium-doped optical fibres (EDFs) based on novel glass compositions and fibre structures in order to support |a much wider erbium gain bandwidth than the state-of-the-art silica based EDFs and the demonstration of wideband EDFAs to increase the transmission capacity of future optical communication networks.

Throughout the PhD, the candidate will have access to state-of-the-artfibre fabrication facilities and laboratories at the ORC and will be working alongside our sponsor. Youwill gain a broad range of technical and professional skills while having the opportunity to publish your work in high-impact journals.

Full tuition fees paid scholarshipwith a stipend of 18,000 tax-free per annum for up to 3.5 years. Overseas students are also encouraged to apply.

The ORC has led the world in optical fibre technology research for the past 50 years. With over 90 state-of-the-art laboratories and 200 researchers working in all areas of photonics, the ORC provides an outstanding interdisciplinary environment for students to grow. Its cluster of 12 photonics spin-out companies provides a natural career path for PhD graduates.

The group has an excellent track record of publishing in high profile research journals and international conferences. Its former PhD and postdoctoral researchers have made successful careers in universities worldwide or as industry scientists and business leaders.

In the first year of your PhD a structured training programme runs alongside the research project, providing a gradual transition from taught degree to open-ended research. Students present their work at conferences worldwide, first-author papers in leading academic journals and emerge with skills at the forefront of glass and fibre optics research

Entry requirements: first or upper second-class degree or equivalent

Closing date: 31/01/2020 or until the position is filled.

Start date: April 2020 (later starts might be acceptable)
