We have experimentally observed, one-dimensional photovoltaic dark spatial soli tons in LiNbO3∶Fe crystal using white light from an incandescent la mp. A blac k-like soliton and a pair of gray solitons are excited from odd and even initial conditions, respectively. The waveguides induced by them can guide both incoher ent white light and coherent light. Their multi-mode structures are clearly obse rved by a probe coherent beam. The experiments demonstrate the presence of one- dimensional white light photovoltaic dark spatial solitons and show that it is p ossible that the coherent beams are controlled and guided by fully incoherent wh ite light dark spatial solitons.
