Description

Laser links have been used between satellites for many years to increase data rates and reduce spectrum crowding. Recently the NASA TBIRD mission demonstrated a breakthrough in using lasers for communication from satellites to ground at 200 Gbps. These speeds are comparable to terrestrial fibre and have the potential to revolutionise modern telecommunications and the space industry. The aim of this project is to understand and expand on the state-of-the-art using a variety of novel approaches including wavefront shaping, alternative laser sources, advanced modulation schemes and new computer algorithms.

Technologically, laser comms are more complex than traditional radio and only recent advances in laser technology and computing have enabled the transition to real-world use. The first in-orbit demonstration flew in 2021 and the UK has recently committed significant funding for academic and industrial research. The space sector is growing faster than ever (CAGR of 9.8%) and is currently restricted by the limitations of radio bandwidth which free-space communications will alleviate. They also promise to help address global challenges including real-time disaster and climate monitoring as well as massively reducing the cost of mobile internet architecture in developing countries.

The programme will take place within the context of a new research group (The Lumen Lab) at Nottingham and we are aiming to build a motivated and ambitious team operating in a supportive and friendly research culture that supports diversity, team cohesion and individual needs. The lab leader (Peter) has previously run multiple start-ups including Exobotics, ProSpectral and Nanomation and is eager to support future commercialisation projects with students and alumni of the Lumen Lab.

We are looking for smart, driven and creative people with the ability to adapt and learn in a fast-moving area. Because of this, we will focus selection on mathematical and engineering aptitude rather than domain knowledge and we encourage applications from a wide array of backgrounds. We will teach, learn or develop the necessary implementation knowledge within the Lumen Lab. Specifically, you will learn skills in research and communication as well as teaching and public speaking. You will also become proficient in technologies including signal processing, machine learning, optical systems, system design and coding in languages such as C++/MATLAB/Python.

Alongside the research programme, the role will include opportunities for travel to conferences, public speaking, and network building. The University of Nottingham is passionate about supporting enterprise and students will be encouraged to pursue successful projects to commercialisation.
