摘　　要：本文讨论了光纤零色散波长的离散对光纤中四波混频效率的影响 ,导出了多段均匀零色散波长光纤输出的四波混频光波强度的表达式 ,进而对该式进行了推广 ,导出了一般情况下的表达式 .最后我们对几种具体情形进行了计算 .计算结果表明当光纤的零色散波长存在漂移时 ,光纤中四波混频效率显著降低 .而且光纤零色散波长漂移的幅度和分布规律以及泵浦光波长的选取对光纤四波混频效率也有重要影响 .The effect of the zero dispersion wavelength deviation along the fiber on the efficiency of Fourwave mixing (FWM) has been studied,and the expression of the amplitude of FWM wave in multisegment fibers with uniform zerodispersion wavelength has been derived.Then we extended this expression and got the general expression.At last,we calculated and discussed some practical situations.The results indicated that when the zerodispersion wavelength along the fiber has a large deviation,the efficiency of FWM decrease markedly.The distribution of fiber zerodispersion wavelength and its fluctuation amplitude has important effect on efficiency of FWM.And the select of pumping wavelength is also important for the efficiency of FWM.
