| 摘 要： | 仿真研究了在三阶色散影响下色散管理光孤子系统的传输特性。利用分布傅立叶方法对非线性薛定谔方程进行了数值求解,同时讨论了在色散管理孤子系统中应用三阶色散补偿对传输特性的影响。仿真结果表明,三阶色散对色散管理孤子脉冲形状和频谱都有明显的影响,并建议在长距离高比特率的色散管理孤子系统中应用三阶色散补偿技术。

| Abstract: | The properties of an optical soliton pulse propagating in the dispersion-managed(DM) system with the influence of third-order dispersion(TOD) are studied.Starting from the modified nonlinear Schr?dinger equation(NLSE),a split-step Fourier transform method has been used to derive the numerical solution of the NLSE.The influences of third-order dispersion compensation are discussed.The results show that the third-order dispersion has the obvious effect on the pulse's profile and spectrum,and the third-order d... |
