Magnetic-field driven hybridization of heavy- and light-hole Rydberg excitons in GaAs quantum wells
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
We present a combined theoretical and experimental study of ground and excited Rydberg exciton states in wide GaAs quantum wells exposed to a magnetic field in the Faraday geometry…
Very strong light-matter coupling in patterned GaAs heterostructures
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
The very strong light-matter coupling regime enables the non-perturbative modification of matter properties via light. Using a patterned GaAs/AlGaAs waveguide with twelve wide quan…
Pulse, polarization and topology shaping of polariton fuids
Lorenzo Dominici, David Colas, Stefano Donati +9
Here we present different approaches to ultrafast pulse and polarization shaping, based on a ``quantum fluid'' platform of polaritons. Indeed we exploit the normal modes of two dim…
Dynamical universality in a driven quantum fluid of light
Ivan Gnusov, Paolo Comaron, Antonio Gianfrate +6
Universal scaling near phase transitions is one of the central ideas of physics, linking the growth of spatial correlations to the slowing down of dynamics. So far, direct experime…
Low-power multi-mode fiber projector overcomes shallow neural networks classifiers
Daniele Ancora, Matteo Negri, Antonio Gianfrate +5
In the domain of disordered photonics, the characterization of optically opaque materials for light manipulation and imaging is a primary aim. Among various complex devices, multi-…
Directional optical parametric amplification in a hyperbolic metamaterial
Antonio Gianfrate, Dimitrios Trypogeorgos, Paolo Comaron +5
Optical parametric amplification (OPA) comprises essentially a nonlinear four-wave mixing process in which a "pump" and a "signal" field give rise to an "idler" field under certain…
