|
摘要
带宽容量需求的快速增长驱动光纤通信技术不断演进,目前多芯光纤复用、少模光纤复用、少模多芯光纤复用和轨道角动量模式复用等空分复用技术成为业界的关注焦点。基于此,对空分复用技术涉及的新型光纤设计、模式转换与控制、信道复用/解复用、光放大等关键技术及其研究进展进行了分析,同时对其技术特征进行了对比总结,并对光纤通信空分复用技术目前存在的问题和未来发展的应用前景进行了探讨和展望。
The evolution of optical fiber communication technology is driven by the ceaseless growth of capacity demand of Internet. Space division multiplexing(SDM) based on multi-core fiber, few-mode fiber, few-mode multi-core fibers and orbital angular momentum has become the focus of academy and industry. Key technologies and latest research progress were reviewed, including novel fiber design, spatial mode conversion, spatial channel de/multiplexing and optical amplification. Based on the comparison and analysis of four kinds of SDM technologies, their bottlenecks and potential future application were also discussed.
