Abstract

Light with a complex structure has become a powerful tool in many studies in classical and quantum optics. Here, we introduce a visual representation of light that is structured simultaneously in space, frequency, and polarization in the form of a higher-order Poincaré sphere and describe interesting links to its fundamental counterpart. We leverage the description to show and experimentally generate light possessing all possible polarization states across its spatiospectral shape, which we term spatiospectral Poincaré beams. By extending the powerful description of higher-order Poincaré spheres to the spatiospectral domain, our work will help to gain a deeper understanding and to develop beneficial applications of structured light.

高阶 Poincaré 球和空间谱 Poincaré 光束
具有复杂结构的光已成为许多经典和量子光学研究的有力工具。在这里,我们介绍了一种同时具有空间、频率和偏振结构的高阶波恩卡莱球形光的视觉表示法,并描述了它与其基本对应物之间的有趣联系。我们利用这一描述来展示并通过实验生成在其空间谱形状上拥有所有可能偏振态的光,我们称之为空间谱波恩卡莱光束。通过将高阶波恩卡莱球的强大描述扩展到空间光谱领域,我们的工作将有助于更深入地理解结构光并开发其有益应用。
