摘　　要：从非线性薛定谔方程出发,导出了Compton散射下全内反射光子晶体光纤中色散缓变管理孤子脉冲传输的准非线性薛定谔方程.数值模拟结果显示:耦合光能使孤子脉冲比散射前有更大的压缩效应,更剧烈振荡效应,更严重的偏离孤子形态效应.为保持孤子形态传输,应尽量避免Compton散射发生.From the nonlinear Schroedinger equation, the quasi-nonlinear Schroedinger equation of the soliton pulse propagation with slowly decreasing dispersion management soliton in the total internal reflective photonic crystal fibers under Compton scattering has been worked out. Numerical simulation shows that the coupling optical pulses can have greater compressed effect of the soliton, acute vibra- tion effect of the soliton and acute diverging sohton state effect than that before the scattering. For keeping the propagation of the solitom state in the fiber, Compton scattering must be avoided as much as possible.
