摘要

光子的总角动量（TAM）作为一种固有的自由度，由自旋角动量和轨道角动量组成，近年来激发了许多先进的应用，引起了人们的广泛关注。根据需要探测TAM和调整波束的TAM频谱对于基于TAM的场景具有重要意义。我们在理论和实验上都提出了一种能够实现可调TAM操作的TAM处理器。这种处理器由一组准对称单元组成，每个单元由一对通过聚合液晶制造的衍射光学元件组成。实验采用了四十二个单TAM态来证明这一概念。有利的结果表明了良好的TAM状态选择性能，这使得它对高速大容量数据传输、光学计算和高安全性光子加密系统特别有吸引力。

Photon total angular momentum manipulation

. As an inherent degree of freedom, total angular momentum (TAM) of photons consisting of spin angular momentum and orbital angular momentum has inspired many advanced applications and attracted much attention in recent years. Probing TAM and tailoring beam ’ s TAM spectrum on demand are of great significance for TAM-based scenarios. We propose both theoretically and experimentally a TAM processor enabling tunable TAM manipulation. Such a processor consists of a set of quasi-symmetric units, and each unit is composed of a couple of diffraction optical elements fabricated through polymerized liquid crystals. Forty-two single TAM states are experimentally employed to prove the concept. The favorable results illustrate good TAM state selection performance, which makes it particularly attractive for high-speed large-capacity data transmission, optical computing, and high-security photon encryption systems.
