摘要
数值方法研究了横向非周期调制Kerr介质中所支持的空间光孤子。数值模拟结果显示研究模型存在三种类型空间光孤子:低功率下的双峰孤子,高功率下的基本孤子和稳定传输的双极孤子。应用线性稳定性分析方法研究了三种类型空间光孤子稳定传输的稳定谱,总结出三种类型光孤子稳定传输的条件。
Spatial optical solitons were studied in Kerr medium with transverse nonperiodic modulation by numerical method. The results of numerical simulation show that there are three kinds of spatial optical solitons. They are petronas soliton, basic soliton under the conditions of lower and higher power of lightrespectively, and bipolar soliton characterized by stable transmission. The stability analysis of the three kinds of spatial optical solitons based on the linear stability is carried out to obtain the stable spectrum in stable transmission, from which the transmission conditions are generalized for stable transmission of the three kinds of spatial optical solitons
