Mutually incoherent wave packets in multicomponent spatial solitons

A description is given of a new class of multicomponent solitons corresponding to stable propagation, in a nonlinear medium, of two or more wave packets which are mutually incoherent, but are matched in respect of the intensity distributions. Such solitons appear as a consequence of cross-modulation self-trapping of zeroth and higher-order modes in a shared nonlinear waveguide formed by these packets.
