非相干饱和光折变空间光孤子对的半解析研究

Semi-analytical study of incoherently coupled spatial optical soliton pairs in saturable photorefractive media

用函数级数展开方法讨论和计算了非相干饱和光折变空间孤子对,针对较普遍性,从几个方面论证了解的收敛性及其演化的稳定性.并首次从系统的计算和讨论中得出在饱和参量一定的光折变介质中,其孤波的特性受到一定的限制.

Incoherently coupled spatial optical soliton pairs in saturable photorefractive media is studied by using function progression expand method, a more general case comparing to the special one under a restrict condition in reference[ 9 ] has been discussed in this paper, The convergence property and the evolution stability of the solution is argued from several respects, After a systematic calculation and discussing, it is first shown that the property of incoherently coupled spatial optical soliton pairs in saturable photorefractive media is restricted under certain condition.
