Incoherent two-color pulse compounds.

We study the dynamical evolution of two-frequency pulse compounds, i.e., intriguing bound-states of light, kept together due to their incoherent interaction. A special class of solutions of such compounds is found to be describable in terms of a simplified model. They entail generalized dispersion Kerr solitons and yield their corresponding metasolitons. We use these solutions to study when the interaction of their constituent pulses is independent of their phase. These results are relevant to understand the complex collision dynamics of quasi-group-velocity-matched solitons across a vast frequency gap.
