Spatio-temporal equilibrium thermodynamics of guided optical waves at positive and negative temperatures
Lucas Zanaglia, Josselin Garnier, Claire Michel +5
Optical thermalization has been recently studied in the 2D spatial evolution of (quasi-)monochromatic light waves propagating in multimode waveguides. Here, we investigate the spat…
Irreversible thermalization vs reversible dynamics mediated by anomalous correlators: Wave turbulence theory and experiments in optical fibers
T. Torres, J. Garnier, L. Zanaglia +8
We theoretically and experimentally investigate spontaneous self-organization in a conservative (Hamiltonian) turbulent wave system, operating far from thermodynamic equilibrium. O…
Spatio-temporal thermalization and adiabatic cooling of guided light waves
Lucas Zanaglia, Josselin Garnier, Iacopo Carusotto +3
We propose and theoretically characterize three-dimensional spatio-temporal thermalization of a continuous-wave classical light beam propagating along a multi-mode optical waveguid…
Wave turbulence, thermalization and multimode locking in optical fibers
M. Ferraro, K. Baudin, M. Gervaziev +9
We present a comprehensive overview of recent advances in theory and experiments on complex light propagation phenomena in nonlinear multimode fibers. On the basis of the wave turb…
Bridging Rayleigh-Jeans and Bose-Einstein condensation of a guided fluid of light with positive and negative temperatures
Lucas Zanaglia, Josselin Garnier, Sergio Rica +5
We consider the free propagation geometry of a light beam (or fluid of light) in a multimode waveguide. As a result of the effective photon-photon interactions, the photon fluid th…
