Research Associate in Quantum Fibre Photonics; SSBAAY

We invite applications for an exciting opportunity in the Centre for Photonics at the University of Bath . The role is available for up to 7 months as a Postdoctoral Research Associate position to develop advanced optical fibre technologies for ultraviolet (UV-C) quantum key distribution (QKD) in satellite communication networks. This well-resourced and collaborative project is led by the University of Bristol , with partners at the Universities of Strathclyde and York and Fraunhofer UK , and aims to extend the security benefits of quantum communication to a truly global scale.

Working closely with our collaborators, you will contribute to the development of a hollow-core optical fibre designed to operate in the UV-C spectral region (100–280 nm). The fibre will act as a mode-filtering solution that ensures secure quantum key distribution without disturbing the polarisation encoding—addressing one of the most challenging aspects of satellite-based quantum communication systems .

You will design, fabricate, and characterise hollow-core fibres that are single-moded at UV-C wavelengths and exhibit temperature- and stress-independent polarisation behaviour . Your work will draw on the University of Bath’s research-grade optical fibre fabrication cleanroom and state-of-the-art photonics laboratories. The project offers an opportunity to expand your expertise in fibre fabrication, UV photonics, and quantum technologies , and to contribute to the development of a pathfinder platform for future global quantum networks .

You will hold (or be close to completing) a doctorate in experimental photonics, quantum optics, or a closely related discipline . Strong experimental skills and a solid understanding of optical wave guides and light–matter interactions are required. Experience with optical fibre fabrication, hollow-core fibre, or ultraviolet photonics will be advantageous but is not essential.

The Centre for Photonics is a collaborative research environment of around 50 academics, researchers, and postgraduate students. The Department of Physics at the University of Bath is a research-led department committed to providing a supportive and inclusive workplace . We strongly encourage applications from groups typically under-represented in UK physics departments.

This is a full time (36.5 hours per week) fixed term role with an expected start date of September 2026 until March 2027.

Informal enquiries should be directed to Dr Kristina Rusimova ( ).

As a member of Research Staff at the University of Bath, you will be encouraged to take up a minimum of 10 days professional development pro rata per year.

A lower grade offer may be made (Grade
6) with comparable reduction in responsibilities and amendment in job title to Research Assistant, if a suitable applicant cannot be found to fill the Grade 7 position. Applicants will need to be within six months of their course completion date and will be promoted to Research Associate once their PhD has been awarded.
