Abstract
Theoretical model of two laser beams propagating in a biased serial photovoltaic photorefractive crystal circuit is first developed and the forming conditions of three different kinds of separate spatial soliton pairs are discussed. Studies on the interaction between two solitons in one soliton pair show that only the dark soliton can affect the other, whereas the bright one cannot. The asymmetry comes from our results determined under the limit of the spatial extent of the optical beam being much less than the width of the crystal. Finally, potential application of this unilateral effect is discussed.
