We report on the observation of two dimensional disorder-induced spatially localized states in a disordered optical fiber. We show evidence of a nonlinear effect of thermal origin, and measure the localization length versus the input power. We also report on the nonlocal interaction involving various localizations and the resulting collective dynamics. Results are interpreted in terms of a two-dimensional nonlinear Schroedinger equation with a random potential and a nonlocal nonlinearity.

Abstract
We report on the observation of two dimensional disorder-induced spatially localized states in a disordered optical fiber. We show evidence of a nonlinear effect of thermal origin, and measure the localization length versus the input power. We also report on the nonlocal interaction involving various localizations and the resulting collective dynamics. Results are interpreted in terms of a two-dimensional nonlinear Schroedinger equation with a random potential and a nonlocal nonlinearity.File in questo prodotto:
