Soliton formation from a pulse passing the zero-dispersion point in a nonlinear Schrödinger equation

S. R. Clarke, R. H. J. Grimshaw, Boris A. Malomed

We consider in detail the self-trapping of a soliton from a wave pulse that passes from a defocussing region into a focussing one in a spatially inhomogeneous nonlinear waveguide,…
