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…
Competing Auger-Like and Intraband Excitations Drive Anomalous Modulations in 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…
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…
Single-mode emission by phase-delayed coupling between nano-lasers
T. V. Raziman, Anna Fischer, Riccardo Nori +10
Near-field coupling between nanolasers enables collective high-power lasing but leads to complex spectral reshaping and multimode operation, limiting the emission brightness, spati…
Mode visualisation and control of complex lasers using neural networks
Wai Kit Ng, T. V. Raziman, Dhruv Saxena +7
Understanding the behaviour of complex laser systems is an outstanding challenge, especially in the presence of nonlinear interactions between modes. Hidden features, such as the g…
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…
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…
Surface lattice resonance lasers with epitaxial InP gain medium
Anna Fischer, Toby Severs Millard, Xiaofei Xiao +7
Surface lattice resonance (SLR) lasers, where gain is supplied by a thin film active material and the feedback comes from multiple scattering by plasmonic nanoparticles, have shown…
Second harmonic generation at a time-varying interface
Romain Tirole, Stefano Vezzoli, Dhruv Saxena +6
Time-varying metamaterials rely on large and fast changes of the linear permittivity. Beyond the linear terms, however, the effect of a non-perturbative modulation of the medium on…
Fluorescence enhancement in topologically optimized gallium phosphide all-dielectric nanoantennas
Cynthia Vidal, Benjamin Tilmann, Sunny Tiwari +4
Nanoantennas capable of large fluorescence enhancement with minimal absorption are crucial for future optical technologies from single-photon sources to biosensing. Efficient diele…
