SelfDeflection Characteristics of Dark Photovoltaic Spatial Solitons in Closed Circuit
The selfdeflection characteristic of dark photovoltaic spatial solitons in onedimensional stable closed circuit is investigated by taking diffusion effects into account by use of numerical method. The results show that dark photovoltaic spatial soliton possesses a selfdeflection process in the direction of the crystal’s axis during propagation and the center of the dark solitary beam moves on a parabolic trajectory. The selfbending distance of the dark solitary beam increases monotonously with the photovoltaic field and the solition input intensity. The self-deflection of dark photovoltaic solitons is very different from that of bright ones.
