Orbital angular momentum
As they propagate, some light beams rotate hence carry angular momentum. When light strikes a particle its radiation pressure pushes it away, but the angular momentum spins it. We use this light to power miniature machines, make tests of quantum mechanics and improve communication systems.
Light from a laser pointer can move microscopic particles like individual cells and bacteria. We use computer controlled holograms to split a single laser into many beams each controlling a particle. Using high-speed cameras we watch, listen and through advanced interfaces feel the micro world.
The Optics Group play a leading role in one of the UK’s four Quantum Technology Hubs. QuantIC will link world-leading quantum technologists with global industry leaders to transform imaging in alignment with industry priorities.
Together we will pioneer imaging and sensing systems with breakthrough functionality by developing a family of quantum-enhanced multidimensional cameras operating across a range of wavelengths, timescales and length-scales.
