我们从理论上提出并通过实验验证了一种将q波片和螺旋相位片相结合的方法，以在混合阶庞加莱球上产生任意矢量涡旋光束。我们证明了矢量涡旋光束可分解为矢量光束和涡旋，因此可通过依次使用q波片和螺旋相位片来实现其产生。所产生的矢量光束、涡旋以及矢量涡旋光束得到了验证，并与预测结果高度吻合。需要指出的另一个优点是，螺旋相位片和q波片均制作在二氧化硅基底上，这表明将这两种结构集成在单个片子上具有潜在可能性。基于一种紧凑的透射型变换方法，我们的方案在未来的集成光学器件中可能具有潜在应用。（C）2016中国激光出版社
We propose theoretically and verify experimentally a method of combining a q-plate and a spiral phase plate to generate arbitrary vector vortex beams on a hybrid-order Poincare sphere. We demonstrate that a vector vortex beam can be decomposed into a vector beam and a vortex, whereby the generation can be realized by sequentially using a q-plate and a spiral phase plate. The generated vector beam, vortex, and vector vortex beam are verified and show good agreement with the prediction. Another advantage that should be pointed out is that the spiral phase plate and q-plate are both fabricated on silica substrates, suggesting the potential possibility to integrate the two structures on a single plate. Based on a compact method of transmissive-type transformation, our scheme may have potential applications in future integrated optical devices. (C) 2016 Chinese Laser Press
