摘    要:在考虑了增益介质的色散、非线性效应、增益以及损耗后,推导出超短光脉冲在分布式光纤放大器中的基本传输方程,采用分步傅里叶变换法数值模拟了皮秒光脉冲的放大传输状态,重点分析了群速度色散和三阶色散对光脉冲特性的影响。

关 键 词:分布式光纤放大器  传输特性  群速度色散  三阶色散:光脉冲

Abstract:Taking into account dispersion,nonlinear effect,gain and loss of gain medium,the basic propagation equation that an ultrashort optical pulse meets in distributed fiber amplifier has been derived.The amplification and propagation states of a picosecond optical pulse have been simulated numerically using split-step Fourier transform method,and the influences of group velocity dispersion and the third-order dispersion on the characteristics of the optical pulse have been analysed mainly.
Keywords:distributed fiber amplifier  propagation characteristics  group velocity dispersion  the third-order dispersion  optical pulse
