Dark incoherent soliton splitting and "phase-memory" effects: Theory and experiment. 
We report on an experimental observation of dark incoherent soliton Y splitting.  The effects of incoherence on the evolution of incoherent dark soliton doublets are investigated both theoretically and experimentally.  We show that the dynamics of these incoherent self-trapped entities are associated with strong "phase-memory" effects that are otherwise absent in the linear regime.
