A description is given of a new class of multicomponent solitons corre
sponding 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.
