摘要
在分步傅里叶算法求解非线性薛定谔方程的基础上,发展了一种动态自适应算法,以达到对时间窗口和步长的动态选择。该算法解决了数值计算过程中由于无法事先估计传输后时域范围而可能引起的仿真结果失真,同时通过对步长的动态选择大大提高了计算效率。在非线性光纤光学、光孤子传输等领域应用该算法都能取得较好的效果。
A dynamic and adaptable algorithm for choosing the time - window and step size is given, based on the split - step Fourier method for miring the nonlinear Sohrodinger equation （NLSE）. The algorithm can avoid the distortion which results from the improper time domain in numerical calculation, and also can enhance the calculation efficiency by dynamic choice for step size. It achieves good performance in nonlinear optic fiber and optical soliton transmission problems.
