论文摘要
我们在理论和实验性相干诱导的具有极化奇点的通用和高阶矢量涡流束的极化变化。突出的去极化对焦点的部分相关矢量涡流束减小横向相关宽度，这提供了一种塑造强度曲线和极化程度（DOP）的手段，同时保留了极化分布。发现强度变化和DOP-DIP取决于光束的极化奇异性指数。我们的结果可能会在目前使用各种类型的矢量涡流梁预测的无数应用中提供额外的自由度。
We demonstrate theoretically and experimentally coherence-induced polarization changes in generic and higher-order vector vortex beams with polarization singularity. The prominent depolarization on decreasing transverse correlation-width in focused partially coherent vector vortex beam provides a means to shape the intensity profile and the degree of polarization (DOP) while preserving the polarization distribution. The intensity variation and DOP-dip are found to be dependent on the polarization singularity index of the beam. Our results may provide an additional degree of freedom in the myriad of applications presently projected with various types of vector vortex beams.
