本文对双折射光子晶体光纤（PCFs）中产生的宽带超连续谱（SC）的偏振特性进行了数值研究。模拟基于考虑量子噪声的广义耦合非线性薛定谔方程。仿真结果表明，由于矢量调制的不稳定性，SC光谱的脉冲间极化状态存在波动。我们在几种模拟条件下研究了SC光谱的偏振稳定性和均匀性，并讨论了在不同偏振要求的应用中双折射pcf中SC的产生。
We present a numerical study of the polarization properties of the broadband supercontinuum (SC) generated in birefringent photonic crystal fibers (PCFs). The simulations are based on generalized coupled nonlinear Schrodinger equations with quantum noise taken into account. The simulations illustrate the complicated polarization behavior in the SC spectra and show that the pulse-to-pulse polarization state of SC spectra fluctuates because of vector modulation instability. We investigate the polarization stability and uniformity of SC spectra under several simulation conditions and discuss generation of the SC in birefringent PCFs for applications with various polarization requirements.
