Graph-theoretic design of lasing networks for physical vision
Paul Obernolte, Jakub Dranczewski, Yixiu Yin +10
Physical neural networks perform learning through the intrinsic nonlinear dynamics of matter. Optimising their design presents a considerable challenge: complex many-body physics c…
Programmable Synthetic Motion at a Time-Varying Interface
A. C Harwood, D. Cielecki, T. V. Raziman +3
Space-time metamaterials that exhibit synthetic motion promise arbitrary control over the momentum, frequency and energy of scattered light, but realising the required space-time m…
Intraband and Interband Competition Drives Ultrafast Modulations of Indium Tin Oxide
Anthony C Harwood, Sean Z J Lim, T V Raziman +7
Transparent conducting oxides near their epsilon-near-zero frequency exhibit near-unity ultrafast modulations of the refractive index which have enabled the field of time-varying m…
Few-Shot Neuromorphic Vision in a Nonlinear Photonic Network Laser
Wai Kit Ng, Jakub Dranczewski, Anna Fischer +11
With the growing prevalence of AI, demand increases for hardware that mimics the brain's ability to extract structure from limited data. In the retina, ganglion cells detect featur…
Surface Plasmon Polariton Excitation in Time-modulated Media
T. V. Raziman, Marie Touboul, Riccardo Sapienza +2
Surface plasmon polaritons (SPPs) are central to application areas such as sensing, energy harvesting, and nanoscale optics, and are typically excited via spatial structuring -- an…
Space-Time Optical Diffraction from Synthetic Motion
A. C. Harwood, S. Vezzoli, T. V. Raziman +7
The interaction of light with objects and media moving at relativistic and superluminal speeds enables unconventional phenomena such as Fresnel drag, Hawking radiation, and light a…
