Abstract :
In this work, we provide a theoretical explanation of this phenomenon through the study of the corresponding soliton solutions. Our analysis identifies the appearance of a threshold for nonlinear self-focusing, which can be selected by varying the wavenumber mismatches, and it also predicts an effective nonlinearity saturation effect.
