An example is given using split step Fourier method. 采用分步傅里叶法对具体实例进行数值求解,验证了讨论结果。
Secondly, making use of the split step Fourier transform and Monte-Carlo method, we simulated the cross-phase modulation instability in active normal and anomalous dispersion fibers with fluctuation of phase noise. 由于相位噪声涨落,利用分裂步长傅里叶变换法与MonteCarlo法,模拟了有源放大器链路中反常色散和正常色散情况下的调制不稳定性。
The paper only compared four representative methods, that is Split Step Fourier(SSF) ( SSF ), Fourier Finite Difference ( FFD ), Generalized Screen Propagators ( GSP ) and Finite Difference in Space Frequency Domain ( XWFD ). 本文仅比较了其中四种具有代表性的方法,即分步傅里叶法(SSF)、傅里叶有限差分法(FFD)、广义屏法(GSP)和空间&频率域有限差分法(XWFD)。
