Transverse instability of incoherent solitons in Kerr media
2001
Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics
We calculate the growth rate of the small-amplitude perturbations superimposed on a one-dimensional soliton that is fully coherent in the self-trapping dimension, yet uniform and partially incoherent in the other transverse dimension. Such solitons become transversely stable only if the correlation distance is below a specific threshold value. We show that this threshold for transverse instability fully coincides with the threshold value for modulational instability.
