摘要:

提出了一种在基于非均匀双折射超颖表面的高阶庞加莱球上产生柱面矢量光束并实现其偏振演化的简便方法。通过超颖表面的局部偏振变换,可以将具有均匀椭圆偏振的光束转换成具有任何期望偏振分布的矢量光束。测量了输出光的Stokes参量,结果与理论预测吻合较好。我们的方法可以提供一个方便的方法来产生CV光束,这有望在信息编码和量子计算中有潜在的应用。

英文摘要:

We present a simple and convenient method to yield cylindrical vector (CV) beams and realize its polarization evolution on higher-order Poincare sphere based on inhomogeneous birefringent metasurface. By means of local polarization transformation of the metasurface, it is possible to convert a light beam with homogeneous elliptical polarization into a vector beam with any desired polarization distribution. The Stokes parameters of the output light are measured to verify our scheme, which show well agreement with the theoretical prediction. Our method may provide a convenient way to generate CV beams, which is expected to have potential applications in encoding information and quantum computation.
