About the project
This PhD project will focus on developing cutting-edge optical fibre amplifier technologies designed to reduce power use, lower the cost-per-bit, and enhance overall data capacity.
Optical fibre networks form the backbone for the internet, transmitting 99% of the world’s data at the speed of light and playing a critical role in the digital transformation of our society and economy. However, the environmental impact of the internet is significant, accounting for ~10% of the world’s total electricity consumption and 3.7% of global CO2 emissions. As data traffic continues to grow, there is an urgent need for energy-efficient technologies to support green optical communications.
A key contributor to power consumption in telecommunication networks is optical fibre amplifiers, which is essential for boosting signals every 80-100 km in long-haul transmission systems. In subsea networks, power consumption directly limits data capacity, making energy-efficient amplifiers critical.
Central to this research is Space Division Multiplexing (SDM), a technique that utilizes multiple channels (e.g. multiple cores within a single fibre) to improve optical amplification efficiency.
Our research team has been a leader in SDM technology, contributing to several landmark EU and UK projects. Our notable achievements include:
- developing the world’s first multimode erbium-doped fibre amplifiers
- setting a GUINNESS World Record for SDM transmission
- winning the prestigious EU HORIZON prize for overcoming the optical transmission barrier
- successfully commercializing SDM amplifier technology
This project offers a balance of simulation and experimental work, providing the successful candidate with the opportunity to join a globally recognized research group equipped with state-of-the-art laboratories.
The candidate will also have the chance to collaborate with industrial partners, ensuring that their work drives real-world impact through innovation in energy-efficient optical communications.
