My research is based upon the generation and applications of structured light, in particular light carrying orbital angular momentum (OAM). It ranges from understanding the fundamental properties of this light to investigating its behaviour in various nonlinear systems, including demonstrating for the first time the mechanism behind optical rogue waves, to potential applications in quantum communication, ocean optics, nonlinear beam propagation and interaction with chiral molecules.
We are planning to build a new device to measure beam attenuation that exploits a recently developed understanding of a quantum property of photons called orbital angular momentum, OAM. We can control this quantum state of light and generate a beam of light with a defined OAM state. When such a beam of light experiences a scattering event, the OAM state changes by a defined, quantum amount that we can easily identify. We can use this change of quantum state to effectively label scattered photons and discriminate them from directly transmitted photons. This means we can measure the number of photons that make it across a volume of water without being absorbed or scattered, without being affected by the scattering collection error that causes problems for current instruments. Our device will then be significantly more accurate than what is currently available and will help researchers and other end-users make significantly better and consistent measurements of what is an extremely important optical property of natural water systems."
