Hi everyone, hope you had a great summer! 🌞 This academic year will start on a high note for us as we have the pleasure to welcome Prof. John Dudley for an amazing seminar on Friday 8th of October 2PM UK time ➡️ register here, everyone welcome! eventbrite.co.uk/e/prof-john-du…

Hi everyone! My handball team and I will be running a 10k next month (better start training 🥲) raising money for MSF, I'll be super grateful if you make a donation here justgiving.com/romainruns😃every little bit counts

Hi all! It's this time of the year when we go out in the cold british weather to run and raise money for MSF 🥳 please consider making a donation on my page! justgiving.com/fundraising/ro…

The classic Young experiment and its quantum versions produce interference fringes when light goes through two thin cracks across space. But what if you have slits at two different points in time? My latest story — and a brief 🧵 [1/n] nature.com/articles/d4158…

Exciting news from our lab, we have observed temporal diffraction of light from a time-varying metamaterial, and it is now published in Nature Physics nature.com/articles/s4156…🤩 imperial.ac.uk/news/244037/do… 🧵

Vous connaissiez l'expérience des fentes d'Young? Mais saviez-vous qu'elle peut être aussi faite temporellement? Ce phénomène a été mis en évidence grâce à des matériaux qui varient très vite et des lasers ultrarapides Romain Tirole Imperial College London larecherche.fr/physique-mat%C…

Have a look at our new paper out now! Learn about how Jakub Dranczewski optimised the fabrication process of InP microlaser structures to obtain smooth side-walls for high-quality cavities sciencedirect.com/science/articl…

My talk at #CLEOEU2023 is this Friday at 11:30 in Room 14a. I'll talk about "Spectral Control of Coupled InP Nanolasers around Exceptional Points through Selective Excitation". Hopefully see you there! #CLEO #EQEC

Hi everyone, excited to present our work on time diffraction at CLEU EU today at 16:45 in room 4b, come by if you're around! I've also uploaded the slides online romaintirole.com/cleo-eu-2023/ 🙂 #CLEOEU2023 Riccardo Sapienza . Also check out Anna Fischer 's talk on Friday!

New paper from the lab! 🤩 Super-luminal Synthetic Motion with a Space-Time Optical Metasurface, 🔦arxiv.org/abs/2407.10809, Raziman T. V. Romain Tirole

New paper out, my last one as a PhD student! We modulate second harmonic generation in a thin film of Indium Tin Oxide and put forward some cool applications for time-varying physics⏰ Riccardo Sapienza Raziman T. V. Imperial College London nature.com/articles/s4146…

New paper out! We show the temporal version of coherent perfect absorption. Wonderful collaboration with Andrea Alu and Emanuele Galiffi, the lead author, as well as Anthony C. Harwood, Stefano Vezzoli and Romain Tirole. arxiv.org/abs/2410.16426
