About the Project
Co-supervisor Dr Yong Chen
We are looking for a new PhD student with a background in chemistry, materials science and/ or physics to join us to study the surface chemistry of thin glass membranes in hollow core fibres (HCFs).
HCFs are an exciting development in optical fibre technology where light is guided in an air-filled core. At the University of Southampton, we have a world-leading group, which designs, characterises and fabricates state-of-the-art HCFs and we recently reported a new world record low loss for this type of optical fibre.
Now the optical lifetime of these fibres is becoming critical for their successful deployment. The hollow core region is surrounded by a cladding structure formed from thin glass membranes. These membranes can have extreme dimensions, e.g, having a width of only 30 nanometres but extending along the full fibre length (up to several kilometres) and therefore they present a novel and interesting platform for glass surface dynamics. We want to study the interactions between these surfaces and air (or other gas species) within the fibre.
In this project, the student will fabricate new HCFs, with a focus on understanding and quantifying the impact of different fabrication processes on the properties of the glass surfaces within the fibre and linking this to lifetime of the final fibre in various applications. Within this scope, the student will become an expert in both fabrication and characterisation of HCFs, while developing a high level of understanding of glass science. The successful student will work with experienced researchers, have access to a wide range of equipment and work with external partners to maximise the impact of their work.
A fully funded PhD position is available for UK applicants (with an enhanced stipend of £18,000 tax-free per annum for up to 3.5 years.) EU students with no external funding can contend for a small number of competitive scholarships. Students from overseas who have secured some external funding are also encouraged to apply. www.orc.southampton.ac.uk/phd_funding.html

About the Optoelectronics Research Centre
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 https://www.youtube.com/watch?v=N2_6yNQamkU.
Entry requirements: first or upper second-class degree or equivalent
Closing date: applications throughout the year.
Duration: typically 3.5 (full-time)
Assessment: reports at 8 and 16-month stages and an oral examination to determine progression to PhD, awarded after thesis submission and viva voce examination
Start date: typically October (later starts might be acceptable)
