偏振模色散和偏振相关损失的联合作用,会产生不规则的色散现象,这一点不能直接通过琼斯距阵本征分析法的运用进行描述。由此引出了对偏振模色散和偏振相关损失共存条件下的研究。通过对琼斯本征分析法进行修正,来分析存在偏振相关损失条件下偏振模色散的特征距阵,理论分析表明,由于偏振相关损失的影响,即使在忽略差分损耗频率相关性的条件下,偏振模色散的特征距阵也会产生根本性的变化。
The combined effect of polarization-mode dispersion and polarization-dependent loss will produce irregular dispersion phenomena that can not be directly described by the use of Jones’s matrix eigenanalysis. This leads to a study of the coexistence of polarization mode dispersion and polarization-dependent loss. Through the correction of Jones eigenanalysis method to analyze the characteristics of polarization mode dispersion under the condition of polarization-dependent loss, the theoretical analysis shows that due to the influence of polarization-dependent loss, even under the condition of neglecting the correlation of the differential loss frequency, the polarization Mode dispersion characteristics of the matrix will have a fundamental change.
