About This PhD Project

Project Description

Because of their unique properties derived from confining and guiding light in a hollow region rather than in a solid material, hollow optical fibers hold a great promise for a wide range of applications, including high power delivery, gas sensing, metrology, sensing, quantum optics and in particular optical communications.

Remarkable breakthroughs at the ORC over the past few years have shown that data can be transmitted over long distances in a hollow fibre, travelling much faster than in a glass fibre and with comparable data transmission capacity (>50 Tbit/s). For wide deployment of these fibers in data transmission applications, it is however imperative that their attenuation is reduced further. Significant progress made over the past few years has led to the understanding that surface scattering, leakage and microbending contribute to the ultimate attenuation and need to be reduced.

In this PhD project, the candidate will work within a world-leading team to develop theoretical models and/or experiments for the studies of loss mechanisms in hollow fibers, and to develop adequate loss reduction strategies for next generation hollow core fiber technology.

A fully funded PhD position is available for UK applicants. 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.

The PhD programme


The project will be hosted at the Optoelectronics Research Centre (ORC), a world-leading institution in optical fibre technology for the past 45 years. With more than 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. Besides, its cluster of ten photonics spin-out companies provides a natural career paths for PhD graduates.

The group has an excellent track record of publishing in high profile research journals and in leading international conferences. Former PhD and postdoctoral researchers from this group have made successful careers in Universities worldwide or as scientists and business leaders in industry. The quality of our research outputs, the cluster of spin-off companies and the worldwide network of successful alumni place the ORC amongst the top institutes worldwide for doctoral research.

The ORC PhD provides a solid education for a research career, http://www.orc.soton.ac.uk/phdprogram.html. In the first year a structured training programme runs in parallel with the research project, provides a gradual transition from a taught degree to the open-ended research. Students will present their work at conferences worldwide, first-author papers in leading academic journals and will emerge from the PhD with skills at the forefront of glass and fibre optics research https://www.youtube.com/watch?v=N2_6yNQamkU.
