Wei E. I. Sha, Zhihao Lan, Menglin L. N. Chen, Yongpin P. Chen, Sheng Sun

AI总结:

本文系统梳理电磁波的自旋与轨道角动量在有源、无源及经典、量子情形下的形式,并通过谱方法数值演示经典涡旋光束拓扑荷的提取。

摘要:

电磁波的角动量在概念和应用两方面都很重要。在本工作中,我们系统地讨论了两类角动量,即自旋角动量和轨道角动量在各种情形下的表现,例如有源与无源情形,以及经典形式和量子形式。文中还给出了数值结果,展示如何通过谱方法提取经典涡旋光束的拓扑荷。

英文摘要:

Angular momenta of electromagnetic waves are important both in concepts and applications. In this work, we systematically discuss two types of angular momenta, i.e., spin angular momentum and orbital angular momentum in various cases, e.g., with source and without source, in classical and quantum forms. Numerical results demonstrating how to extract the topological charge of a classical vortex beam by spectral method are also presented.
