| 摘 要： | 在导出自相位调制和交叉相位调制共同作用所致相位调制频率啁啾的基础上,数值研究了相位调制频率啁啾与初始啁啾的关系,并对有和无初始啁啾40Gbit/s归零码(RZ)在二阶和三阶色散完全补偿(路径平均色散为0)的色散管理偏振复用孤子传输系统中的传输效果进行计算。结果表明,在输入功率达到一定值时,初始啁啾参量C对相位调制频率啁啾的作用,决定着系统偏振复用孤子技术的成效及传输性能,适当选取初始啁啾参量C能够有效抑制偏振模色散,提高孤子脉冲稳定传输距离。

| Abstract: | After deriving self-phase modulation (SPM) and cross-phase modulation(XPM), under the joint effect of phase modulation freque ncy chirp (PMC),the relationship between PMC and initial chirp,is numerically st udied,the transmission effects of dispersion managed soliton (DMS) in the transm ission system are calculated when there is initial chirp 40Gbit/s return-to-ze ro(RZ) or not.The second-order and third-order dispersion is completely compen sated(the average dispersion being zero).The result indicates that when the inpu t power is fixed ,the effect of initial chirp C on PMC determines the effect and transmission performance of polarization-divided multiplexing soliton tech nique in the system and that choosing properly the value C can effectively r estrain polarization modes dispersion(PMD) and lengthen the distance of stabilit y transmission of soliton pulse. |
