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…
Radiative-channel valley topological laser
Seonyeong Kim, Markus Scherrer, Jakub Dranczewski +3
Active topological photonic systems enable robust light control and new pathways for semiconductor lasing. However, their intrinsically non-Hermitian nature, combining gain, radiat…
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 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…
Controlling lasing around Exceptional Points in Coupled Nanolasers
Anna Fischer, T. V. Raziman, Wai Kit Ng +7
Coupled nanolasers are of growing interest for on-chip optical computation and data transmission, which requires an understanding of how lasers interact to form complex systems. Th…
Saturable time-varying mirror based on an ENZ material
Romain Tirole, Emanuele Galiffi, Jakub Dranczewski +9
We report a switchable time-varying mirror, composed of an ITO-Au stack, which can be efficiently modulated in time with over a ten-fold increase in reflectivity, with a change of…
Two-Colour Interferometry and Thomson Scattering Measurements of a Plasma Gun
J. D. Hare, J. MacDonald, S. N. Bland +6
We present experimental measurements of a pulsed plasma gun, using two-colour imaging laser interferometry and spatially resolved Thomson scattering. Interferometry measurements gi…
