| 摘 要： | 研究了不同调制格式的产生及其偏振模色散补偿性能。首先从实验上得到了不同调制格式的频谱和眼图,并将其输入偏振模色散补偿系统,实现了缓解与补偿的动态结合。其次,从数值上比较和分析了不同调制格式应用于以偏振度做反馈信号的偏振模色散补偿系统后的补偿性能,结果表明,差分相移键控对偏振度的响应度和偏振模色散补偿效果要比传统开关键控好,因此差分相移键控非常适合于以偏振度做反馈信号的偏振模色散补偿系统;而载波抑制码差分相移键控结合了载波抑制码载波抑制特性和差分相移键控的特殊频谱特性,具有最好的偏振模色散补偿效果。

| Abstract: | The generation of different modulation formats and their polarization dispersion compensation(PMD)performance have been studied.Firstly,the eye diagrams and spectrum of different modulation formats through experiment have been obtained,and then the dynamic combination of their mitigation and compensation in PMD have been accomplished.Secondly,the PMD compensation performance with degree of bolarization(DOP)as feedback signal of the mentioned modulation formats has been studied via simulation.It shows that DOP responsibility and PMD compensation performance of differential phase-shift key(DPSK)are better than that of on-off keying(OOK).CSRZDPSK combines the carrier-suppressed characteristic of CSRZ formats and specific spectrum characteristic of DPSK formats,therefore it has the best PMD compensation performance. |
