摘要

本文提出了一种基于分段涡束的信息编码方法。为进行信息编码,我们设计了具有单一均匀强度环和多种拓扑电荷组合的分段涡束。束的半径可任意设计,多个轨道角动量状态沿环叠加。我们将信息编码到发射单元中的分段涡流束中,用于信息传输。由于波束的分段相位结构,信息可以被编码到每个分段中,信息容量大大增加。此外,光束中大量的编码信息组合可以大大提高编码信息的安全性。这种方法在自由空间光通信领域具有巨大潜力。

Information encoding with a segmented vortex beam
In this paper we propose an information encoding method based on a segmented vortex beam. The segmented vortex beam with a single uniform-intensity ring and a combination of multiple topological charges is designed for information encoding. The radius of the beam can be designed to be arbitrary, with multiple orbital angular momentum states superimposed along the ring. We encoded the information into the segmented vortex beam in the transmitting unit for information transmission. Due to the segmented phase structure of the beam, information can be encoded in each segment, and the information capacity is significantly increased. Additionally, enormous combinations of encoded information in the beam can greatly enhance the security of the encoded information. This proposed method has great potential in free-space optical communication.
