论文摘要
我们提出了一种量子光学方法，用于描述两种I型晶体“三明治”配置中刺激的参数降低转换，从而允许向量涡流梁的参数相互作用。我们分析了发生种子载体束的相结合的条件。然后，我们使用两种策略来定义广义的Stokes参数来描述矢量涡流梁的相位共轭。这些允许几何表示，例如高阶庞加莱球体。我们的结果可用于描述和设计使用矢量涡流梁的刺激和自发参数降低转换实验。
We present a quantum optics approach for describing stimulated parametric down conversion in the two type-I crystal "sandwich" configuration, which allows for parametric interaction of vector vortex beams. We analyze the conditions for which phase conjugation of the seed vector beam occurs. We then use two strategies for defining generalized Stokes parameters to describe phase conjugation of vector vortex beams. These allow for geometrical representations, such as higher-order Poincaré spheres. Our results are useful for description and design of stimulated and spontaneous parametric down conversion experiments with vector vortex beams.
