摘要:

我们提出并实验证明,由Pancharatnam-Berry相位光学元件组成的超颖表面可以完全控制光学自旋-轨道角动量转换。我们的方法依赖于超颖表面上的透射和反射之间的临界干涉,以通过对两个入射光束的相干控制来创建具有高输出的主动可调谐和可控转换。所介绍的控制方法是通用的,并可能是一个重要的一步,对实际应用的功能光学器件的发展。

英文摘要:

We propose and experimentally demonstrate that a metasurface consisting of Pancharatnam-Berry phase optical elements can enable the full control of optical spin-to-orbital angular momentum conversion. Our approach relies on the critical interference between the transmission and reflection upon the metasurfaceto create actively tunable and controllable conversion with a high output via coherent control of the two incident beams. The introduced control methodology is general and could be an important step toward the development of functional optical devices for practical applications.
