摘要

轨道角动量(OAM)是自由空间通信、光探测和测距以及遥感等各种应用中使用的电磁波的重要特性。然而,湍流会导致轨道角动量模式之间的能量转移,从而破坏基于轨道角动量的系统,严重影响光学频谱中新出现的场。传统的分析假设湍流参数(Cn2)为常数,而最近的研究则强调了其在特定情况下的随机性。我们的研究引入了一个考虑 Cn2 随机性的新模型。考虑到这一特性,我们的方法可以更好地预测系统性能,并为准确描述和设计弱湍流环境中的通信和遥感系统提供有价值的见解,从而提高其可靠性和效率。

Analyzing the likelihood of OAM mode energy transfer in turbulent environments with stochastic Cn2
Orbital angular momentum (OAM) is a crucial property of electromagnetic waves used in various applications such as free space communication, light detection and ranging, and remote sensing. However, turbulence can disrupt OAM-based systems by causing energy transfer between OAM modes, significantly impacting emerging fields in the optical spectrum. While traditional analyses assumed a constant turbulence parameter (Cn2), recent research highlights its stochastic nature in specific scenarios. Our study introduces a new model that considers the stochastic nature of Cn2. By incorporating this characteristic, our approach provides better predictions of system performance and valuable insights for accurately characterizing and designing communication and remote sensing systems in weak turbulent environments, enhancing their reliability and efficiency.

期刊介绍: Journal of Optics publishes new experimental and theoretical research across all areas of pure and applied optics, both modern and classical. Research areas are categorised as: Nanophotonics and plasmonics Metamaterials and structured photonic materials Quantum photonics Biophotonics Light-matter interactions Nonlinear and ultrafast optics Propagation, diffraction and scattering Optical communication Integrated optics Photovoltaics and energy harvesting We discourage incremental advances, purely numerical simulations without any validation, or research without a strong optics advance, e.g. computer algorithms applied to optical and imaging processes, equipment designs or material fabrication.
