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…
Supersolidity of polariton condensates in photonic crystal waveguides
Davide Nigro, Dimitrios Trypogeorgos, Antonio Gianfrate +3
Condensation of exciton-polaritons has been recently observed in one-dimensional photonic crystal waveguides, exploiting the interplay of long-lived gap confined eigenmodes and neg…
