Project Description
High-capacity ground-to-satellite communications have long relied on microwaves for data transmission, as they have since the very first communications satellites were launched. However, the surge in demand for data-intensive digital services and the evolution of sophisticated satellite-borne sensors have pushed microwave links to their limit, transforming them into a critical data transmission bottleneck.
This is where optical communications come in. Leveraging the unparalleled bandwidth of optical technologies, akin to those powering the internet’s fibre-optic backbone, represents a transformative solution to the challenges faced by ground-to-satellite communication. The potential for over 3 orders of magnitude improvement in transmission capacities stands as a scalable factor for growth, ensuring the long-term competitiveness of satellite communication against other wireless access technologies.
Yet, the transmission of light through Earth’s atmosphere introduces its own set of challenges, primarily weather effects and atmospheric turbulence. This PhD project invites you to embark on ground-breaking exploration of novel methods to overcome these challenges. Cutting-edge approaches, such as using spatial light modulators for precise phase-front correction and harnessing exotic spatial modes (such as orbital angular momentum modes), will be investigated. This endeavour capitalizes on the unique synergy of photonic fabrication facilities and world-leading expertise at the ORC. This project will require a mixture of experimental work to produce hardware solutions to these atmospheric challenges as well as numerical modelling to understand how these solutions will scale to the distances involved with ground to satellite communication.

Entry Requirements
A very good undergraduate degree (at least a UK 2:1 honours degree, or its international equivalent).
Closing Date
Applications are accepted throughout the year. The start date will typically be late September, but other dates are possible.
Funding
For UK students, tuition fees and a stipend at the UKRI rate plus £2,000 ORC enhancement tax-free per annum for up to 3.5 years (totalling around £21,000 for 2024/25, rising annually). EU and Horizon Europe students are eligible for scholarships. CSC students are eligible for fee waivers. Funding for other international applicants is very limited and highly competitive. Overseas students who have secured or are seeking external funding are welcome to apply.
