Structured Light in Turbulence

Mitchell A. Cox, Nokwazi Mphuthi, Isaac Nape, Nikiwe P. Mashaba, Ling Cheng, Andrew Forbes

摘要:

光通信是现代经济的组成部分,几乎取代了所有的电子通信系统。带宽的未来增长似乎即将出现,使用结构光,将信息编码到光的空间模式中,并将其传输到光纤和自由空间中,后者对于解决最后一英里和数字断开的社区至关重要。不幸的是,光的模式很容易失真,并且在自由空间光通信的情况下,湍流是一个重要的障碍。在这里,我们回顾了湍流中结构光的最新进展,首先对核心概念进行了教程式总结,然后重点介绍了该领域的最新技术。我们支持我们的审查与新的实验研究,揭示哪些类型的结构光是最好的湍流,矢量与标量光在湍流中的行为,多样性和复用的权衡,以及如何湍流模型可以利用增强的光信号处理协议。这一全面的论文将是无价的大社区感兴趣的自由空间光通信与空间模式的光。

英文摘要:

Optical communication is an integral part of the modern economy, having all but replaced electronic communication systems. Future growth in bandwidth appears to be on the horizon using structured light, encoding information into the spatial modes of light, and transmitting them down fibre and free-space, the latter crucial for addressing last mile and digitally disconnected communities. Unfortunately, patterns of light are easily distorted, and in the case of free-space optical communication, turbulence is a significant barrier. Here we review recent progress in structured light in turbulence, first with a tutorial style summary of the core concepts, before highlighting the present state-of-the-art in the field. We support our review with new experimental studies that reveal which types of structured light are best in turbulence, the behaviour of vector versus scalar light in turbulence, the trade-off of diversity and multiplexing, and how turbulence models can be exploited for enhanced optical signal processing protocols. This comprehensive treatise will be invaluable to the large communities interested in free-space optical communication with spatial modes of light.
