摘要

轨道角动量（OAM）模构成了电磁场空间分布的完整基集。利用OAM模式的正交性，光纤通信系统可以建立独立的传输信道，从而大大扩展系统容量。此外，将OAM模分复用（MDM）与其他复用技术（如波分复用（WDM））相结合，有可能降低多输入多输出（MIMO）处理的复杂性，并进一步增强基于光纤的通信容量。在本文中，我们回顾了环芯光纤中OAM模式传输的优势，讨论了在保持低串扰的同时支持多种OAM模式的设计策略，并介绍了旨在提高整体传输容量的基于OAM的MDM通信系统。

Recent advances in ring-core fiber for orbital-angular-momentum-based mode-division multiplexing

Orbital angular momentum (OAM) modes constitute a complete basis set for the spatial distribution of electromagnetic fields. By exploiting the orthogonality of OAM modes, optical fiber communication systems can establish independent transmission channels, thereby substantially expanding system capacity. Furthermore, the combination of OAM mode-division multiplexing (MDM) with other multiplexing techniques, such as wavelength-division multiplexing (WDM), offers the potential to reduce the complexity of multiple-input multiple-output (MIMO) processing and further enhance fiber-based communication capacity. In this paper, we review the advantages of OAM mode transmission in ring-core fibers, discuss the design strategies that enable the support of multiple OAM modes while maintaining low crosstalk, and introduce OAM-based MDM communication systems aimed at boosting overall transmission capacity.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
