摘　　要：在对四波混频 (FWM)功率估计的数值仿真中 ,为解决采用固定步长分布 (USSD)方法引起的谐振效应和耗时问题 ,对USSD方法进行了修正 .在窜扰要求不高的情况下 ,此修正方法较之USSD方法和对数步长分布 (LSSD)方法 ,更能满足仿真结果的稳定性要求 .USSD (Uniform Step-Size Distribution) method brings some resonances and needs more computational time when it is used to compute the FWM(Four-Wave Mixing)efficiency in split-step Fourier method simulations. In order to resolve this problem, the modified USSD method and LSSD (Logarithmic Step-Size Distribution) method are deduced and presented according to the FWM efficiency generic formula. Compared with USSD and LSSD method, the modified USSD method is more suitable for reliable simulation requirements.
