| 摘 要： | 在光副载波复用系统中若使用偏振度作为偏振模色散的监测信号将会遇到灵敏度低的问题.本文首先讨论了色度色散和初始啁啾对偏振度的影响,然后找出了影响监测信号灵敏度的因素,并提出了相应的解决方法.使用一个窄带滤波器用来平衡光载波和边带的功率,偏振度对偏振模色散的灵敏度将会明显的增长.

| Abstract: | The problem of low sensitivity will become severely if DOP is used as the monitor signal of DGD in SCM system. This paper firstly analysis the influence of chromatic dispersion (CD) and initial chirp on DOP .Then it will find out the factors that works on the low sensitivity of DOP and suggested an approach solving the problem. This paper uses a narrow-band optical filter to equalize the power of the carrier and one of the sidebands by offsetting the filter from the carrier ,making the sensitivity which DOP to DGD increase. |
