【Abstract】 We have experimentally observed, one-dimensional photovoltai c dark spatial solitons in LiNbO 3∶Fe crystal using white light from an incand escent lamp. A black-like soliton and a pair of gray solitons are excited from o dd and even initial conditions, respectively. The waveguides induced by them can guide both incoherent white light and coherent light. Their multi-mode structur es are clearly observed by a probe coherent beam. The experiments demonstrat e the presence of one-dimensional white light photovoltaic dark spatial solitons and show that it is possible that the coherent beams are controlled and guided by fully incoherent white light dark spatial solitons.更多还原
