Photonics
Photonics, the study of light and its applications, is a cornerstone of technological progress, transforming industries and shaping our future. At ֲý, photonics research drives innovation across fields such as telecommunications, healthcare, manufacturing, and environmental monitoring. From enabling faster and more secure data transmission to creating cutting-edge medical imaging techniques, photonics offers compelling solutions to some of society’s most pressing challenges.
Our photonics research explores the full potential of light through five key areas: novel light sources, high-power laser applications, photonic sensing and measurement, nanophotonics, and biomedical photonics. This work not only advances scientific understanding, it also delivers real-world benefits. For example, high-power lasers enhance manufacturing precision, while photonic sensors enable advanced environmental monitoring and medical diagnostics.
Through partnerships with global industrial and research organisations, our photonics experts are developing technologies that improve efficiency, precision, and sustainability. Our research on nanophotonics, for instance, is enabling ultra-compact photonic devices that redefine imaging and telecommunications. Our research on biomedical photonics will help us to revolutionise healthcare, providing tools for earlier diagnosis, personalised treatments, and minimally invasive surgeries.
Photonics at ֲý is more than a scientific discipline; it is a driver of innovation that impacts how we communicate, manufacture, and care for health and the environment. By pushing the boundaries of light-based technologies, our researchers are creating solutions that will shape a more connected, sustainable, and healthier world.
Photonics is a world-leading area of research expertise at ֲý, recognised in the 2021 Queen's Anniversary Prize for photonics. The Institute of Photonics and Quantum Sciences (IPaQS) is an integral part of a focused research ecosystem, collaborating on aligned projects across our other institutes and global research institutes; The National Robotarium, The Lyell Centre for Earth and Marine Sciences and Technology, The Global Research Institute in Health and Care Technologies, and the iNetZ+ Global Research Institute for Net Zero and Beyond.
By bringing together experts in photonics, and a range of scientific disciplines, in a collaborative environment, the most complex challenges can be tackled. This interdisciplinary approach is strengthened through external partnerships, ensuring the research not only advances scientific understanding but also delivers real-world impact across multiple sectors, from telecommunications to healthcare and precision manufacturing.
