| 摘 要： | 推导了准单色光波情况下高斯脉冲伪随机序列偏振度的简洁数学表达式.理论分析结果表明,偏振度与差分群延迟之间的关系与线路啁啾和光纤色散无关,并且此关系可以由光信号频谱半宽度Δω和分光比γ唯一确定.用10 Gbit/s 7级m序列归零码进行的实验表明:实验结果与理论推导基本一致,从而验证了推导公式的正确性.

| Abstract: | The mathematical expression of DOP with DGD for pseudo random m sequence code using Gauss pulses was derived.Then the relationship was theoretically analyzed and simplified.The result shows that the relationship between DOP and DGD is independent of chirp and fiber dispersion and can be determined by the FWHM of the optical spectrum.Experiments with 10Gbit/s RZ seven stages′ m sequence was given,theoretical calculation and experimental results were compared.The comparison shows that they match closely. |
