Just saw this - Congratulations Jonny!

and 8yrs later (in 2003) you taught me 'Modern Optics' at Durham (I still have the notes and regularly dip into Hecht). You also taught 2 other faculty here at Exeter physics!

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!

and... our program for the upcoming IMAGE SCIENCE🔬 Gordon Research Conference (GRC) is 🎯LIVE🎯. It will take place April 26, 2026 in beautiful tuscany, italy 🇮🇹 🍕 🤌

Please check our stellar line-up, share, and register!

High-speed wavefront shaping focussed: jobs.ac.uk/job/DND534/p...
Application deadline 8th June.

2 postdoctoral researcher positions are available in the Structured Light Group in Exeter (UK). Project focussed on quantum & classical light control through dynamic complex scattering media (see concept picture). Details are below. Drop me an email if you'd like to know more! 🧪💡

We have multiple postdoc openings in *optical computing* 🔦+🤖, *computational microscopy* 🔬+🧠, and *nanophotonics*💡+⚛️. Don't hesitate to get in touch / spread the word!

Project in collaboration with Simon Horsley (Exeter) and Philipp del Hougne (Univ. de Rennes). See here for our paper (open access): www.nature.com/articles/s41...

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...
