Observation of spatial nonlinear self-cleaning in a few-mode step-index fiber for special distributions of initial excited modes
In this paper, we experimentally demonstrate that a nonlinear Kerr effect in suitable coupling conditions can introduce a spatially self-cleaned output beam for a few-mode step-index fiber. The impact of the distribution of the initial excited modes on spatial beam self-cleaning has been demonstrate...
