Photonics

Our strategy is to pursue cutting edge research on laser sources and photonic materials, ranging from early metrology to applications in healthcare and energy.

We have developed and exploited reliable femtosecond Ti:sapphire laser sources, first invented by Prof Wilson Sibbett (emeritus; Royal Medal 2009). We use these to study fundamental physics, including the demonstration of an optical black hole, and precise measurement of exciton diffusion, which is vital for developing organic solar cells. We have pioneered the use of Airy light fields and electron-vortex beams, leading to three patents and a new mode of biomedical imaging. We have used new materials to explore the physics of slow light and of optical chaos.
