摘要: 为了研究不同参量对双光子光折变材料中的刚性光伏空间孤子的影响,推导出了刚性光伏空间孤子的演化方程,根据实际的物理条件,采取一定的数学近似,对演化方程进行化简,从而得出演化方程的亮暗孤子的解析解,并讨论了不同参量,如光伏电场强度、背景暗辐射光强度、启动光强度、吸收系数和光波长对孤子的影响。结果表明,除了光伏电场强度,亮孤子的宽度随其增加而减小之外,亮孤子的宽度都随其它参量的增加而变大,只是变大趋势的速度不同。研究结果可为空间光孤子理论发展提供理论依据。

Abstract: In order to analyze the effect of different parameters on the rigid photovoltaic spatial solitons formed in two-photon photorefractive medium,the evolution equation of such solitons was deduced.According to the practical condition,after the equation was simplified based on approximation,its analytical solutions were obtained,and the effect of different parameters, such as photovoltaic field,dark background radiation,start light,absorption coefficient,and wavelength,on these solitons were also discussed.Results show that with the intensity of photovoltaic field increasing,the full width at half maxim of solitons decreases accordingly and with the other parameters increasing,the full width at half maxim of solitons increases accordingly just at different increasing rates.It turned out that this study results provide theoretic basis for development of the spatial solitons theory.
