Classical optical correlation in beam fields with orbital angular momentum and its application

量子光场的关联性质是量子光学研究的一个重要主题。在对其深入挖掘的过程中,人们在经典光场关联性质方面的研究也取得了一系列重要进展。尤其是结合近二十年来在光信息处理方面备受关注的轨道角动量自由度,观察到许多与高维量子光关联性质相对应的现象。本综述对轨道角动量光束中的经典光关联相关研究进行了总结,介绍了轨道角动量光束中的局域不可分离性及其应用,对空间可分离轨道角动量光束中的经典光关联也做了讨论。特别地,作为一种潜在的量子过程研究平台,还对基于轨道角动量光束的随机行走研究作了介绍。

The correlation feature of quantum light field is an important subject of quantum optics research. With the in-depth study on the subject, the researchers have also made a series of great progress in the correlation of classical light. Especially, by combining the orbital angular momentum of light,which has drawn much attention in the recent 20 years, a series of counterparts of high-dimensional quantum light have been observed. In this review, the related research of classical optical correlation in orbital angular momentum beams is summarized, the local inseparability in orbital angular momentum and its application are introduced, and the classical optical correlation in spatially separable orbital angular momentum is discussed as well. In particular, as a potential quantum process research platform,the random walk research based on the orbital angular momentum of classical light is also introduced.
