Leading the Structured Light Lab, University of Exeter, UK. Research focussed on optics & photonics: wavefront shaping, computational imaging, complex photonics, optical tweezers, laser writing, structured light.
New arXiv paper: "Harnessing the frequency eigenchannels of ultrafast time-varying media", led by Ian Hooper and Simon Horsley at Uni. of Exeter. Translating concepts from spatial "wavefront shaping" to temporal "waveform shaping" through dynamic media moving fast enough to generate new frequencies!

New paper on #ArXiv!
When (coherent) light propagates in a multimode fibre, each mode accumulates a slightly different phase, so the output looks like a random speckle patter.
But it is NOT random!

The radial memory effect in multimode optical fibres
We present a study of a novel memory effect in multimode optical fibres, which manifests itself as an output ring of excess energy at the same radius as an input focussed spot. This effect is robust a...

Happy to share our work published in Nature Photonics: "Threading light through dynamic complex media". We show how to pilot beams of light through the most stable channels within moving scattering media. Special thanks to Chai, Christina & John from the Structured Light Group, Exeter! #Photonics💡

Hello, just arrived on bsky! Looking for fellow optics researchers. To kick things off - here is our latest preprint: arxiv.org/abs/2501.14129 'Self-configuring high-speed multi-plane light conversion'. Lead author José Rocha prefers to go make a cup of tea rather than manually align his MPLC...
