摘要
通过实验方法研究轨道角动量(OAM)态水下传输特性。首先搭建OAM态水下光通信系统,然后通过OAM态展开谱和接收到的初始及其相邻OAM态概率变化曲线来研究其水下传输能力。实验结果表明:随着盐度的增加,初始OAM态的概率明显降低;相邻OAM态的传输概率随着拓扑荷间隔的增加而减少。
Abstract
We study the underwater propagation characteristics of orbital angular momentum (OAM) states by experimental method. We build an underwater optical communication system of OAM states, and then discuss the underwater transmission capacity of OAM states by the spread spectra and the probability curves of the original and adjacent OAM states. The experimental results show that the probability of original OAM state decreases significantly with the increasing of salinity, and the propagation probability decreases with the increasing of topological charge interval.
