Abstract
We investigate theoretically and experimentally one-dimensional bright photovoltaic solitons in LiNbO3:Fe crystal by use of the background illumination. We find that, in LiNbO3:Fe crystal, bright photovoltaic solitons can be obtained with background illumination for κ>1, where κ is the ratio of the background illumination photovoltaic constant to the soliton optical beam's photovoltaic constant. For κ<1, dark photovoltaic solitons are generated. On the other hand, our experiments show good agreement with theoretical prediction for the soliton existence curve in a special intensity ratio.
