Experimental demonstration of the Fermi-Pasta-Ulam recurrence in a modulationally unstable optical wave.
Through a detailed spectral analysis of the propagation of square-shaped laser pulses in optical fibers, we provide the experimental demonstration of the Fermi-Pasta-Ulam recurrence phenomenon in modulationally unstable optical waves ruled by the nonlinear Schrödinger equation.
