【Abstract】 The index refractive profiles of light induced waveguides in photorefractive crystal under the conditions of supporting bright soliton and dark soliton are investigated.It is shown that the reciprocal and the derivative of the logarithm of incident wave intensity determine the index refractive change in the photorefractive crystal,respectively.The contribution of the reciprocal of incident wave intensity to the index refractive change is symmetry but the derivative of the logarithm of incident wave intensity asymmetry.更多还原
