Emergence of criticality through a cascade of delocalization transitions in quasiperiodic chains
V. Goblot, A. Štrkalj, N. Pernet +10
Conduction through materials crucially depends on how ordered they are. Periodically ordered systems exhibit extended Bloch waves that generate metallic bands, whereas disorder is…
Parametric instability in coupled nonlinear microcavities
N. Carlon Zambon, S. R. K. Rodriguez, A. Lemaitre +7
We report the observation of a parametric instability in the out-of-equilibrium steady state of two coupled Kerr microresonators coherently driven by a laser. Using a resonant exci…
Nonlinear Polariton Fluids in a Flatband Reveal Discrete Gap Solitons
V. Goblot, B. Rauer, F. Vicentini +10
Phase frustration in periodic lattices is responsible for the formation of dispersionless flat bands. The absence of any kinetic energy scale makes flat band physics critically sen…
Orbital angular momentum bistability in a microlaser
Nicola Carlon Zambon, Philippe St-Jean, Aristide Lemaître +6
Light's orbital angular momentum (OAM) is an unbounded degree of freedom emerging in helical beams that appears very advantageous technologically. Using a chiral microlaser, i.e. a…
Brillouin Scattering in Hybrid Optophononic Bragg Micropillar Resonators at 300 GHz
M. Esmann, F. R. Lamberti, A. Harouri +9
We introduce a monolithic Brillouin generator based on a semiconductor micropillar cavity embedding a high frequency nanoacoustic resonator operating in the hundreds of GHz range.…
Generation of non-classical light in a photon-number superposition
J. C. Loredo, C. Antón, B. Reznychenko +12
The ability to generate light in a pure quantum state is essential for advances in optical quantum technologies. However, obtaining quantum states with control in the photon-number…
