论文摘要
结构化的光提供更宽的带宽和更高的通信安全性。但是，通过复杂的随机培养基（例如地球大气）的传播通常会引起模式串扰。我们在数值上和实验上表明，光子轨道角动量（OAM）模式的耦合受单个参数的通用函数的控制 - 即使在明显的强度波动的情况下，随机培养基和束的横向相关长度之间的比率也是如此。
Structured light offers wider bandwidths and higher security for communication. However, propagation through complex random media, such as the Earth's atmosphere, typically induces intermodal crosstalk. We show numerically and experimentally that coupling of photonic orbital angular momentum (OAM) modes is governed by a universal function of a single parameter -- the ratio between the random medium's and the beam's transverse correlation lengths, even in the regime of pronounced intensity fluctuations.
