利用数值求解非线性耦合方程，研究了四阶色散对于单泵浦光纤参量放大器增益的影响．计算表明，通过优化泵浦波长和四阶色散值，可以获得大的平坦带宽或者特殊的应用．分析了在大信号输入时对应增益的变化，发现对于泵浦波长大于零色散波长且四阶色散为正值的增益谱影响最大．

The effect of the fourth order dispersion on the gain of FOPA is studied by numerical simulation based on coupled equations. The results show that large flat gain bandwidth or special application can be obtained with optimal pump wavelength and four order dispersion. The influence of large input signal on the gain is investigated, and it is found that the impact reaches the highest when pump wavelength is larger than zero dispersion wavelength and the fourth order dispersion is positive.
