利用全反射光在光纤包层中的横向偏移和渡越时间 ,导出了各向同性光纤的全反射偏振色散公式及双折射光纤偏振色散的修正公式 ,通过模拟计算分析了偏振色散随入射角的变化规律 .
The formulas of total reflection polarization dispersion and birefringence polarization dispersion of isotropic fiber are deduced by using the transverse shift and transit time of total reflection light in the fiber cladding, and the correction formulas of polarization dispersion with incident angle The law of change.
