In an optical experiment, we report a wave turbulence regime that, starting with weakly nonlinear waves with randomized phases, shows an inverse cascade of photons toward the lowest wavenumbers. We show that the cascade is induced by a six-wave resonant interaction process and is characterized by increasing nonlinearity. At low wavenumbers the nonlinearity becomes strong and leads to modulational instability developing into solitons, whose number is decreasing farther along the beam.

Optical turbulence and spectral condensate in long fibre lasers

Numerically optical turbulence is studied using the particular example of a recently created, ultra-long fibre laser to demonstrate that the number of modes has an impact on the condensate's lifetime, and the smaller theNumber of modes, the more resistant is thecondensate to perturbations.

Wave turbulence in integrable systems: nonlinear propagation of incoherent optical waves in single-mode fibers.

The traditional treatment of the wave turbulence theory is revisited to provide a statistical kinetic description of the integrable scalar NLS equation and an analytical expression of the damped oscillations is derived, found in agreement with the numerical simulations of both the NLS and kinetic equations.
