摘要

本文综述了基于低差分模延迟的少模光纤的模分复用系统的最新研究成果，从光纤设计优化到接收机存储器尺寸。首先，对光纤折射率剖面进行了优化，以实现低差分模延迟和低宏观弯曲损耗。然后，我们提出了由纤维缺陷和应力引起的线性模态耦合的半解析模型。最后，对线性模式耦合和差分模式延迟之间的相互作用进行了数值和解析研究，从而量化了给定光纤跨度所需的接收器内存。

On the feasibility of mode-division multiplexed transmission over few-mode fibres

This paper reviews our most recent results on mode-division multiplexing systems based on few-mode fibres with low differential mode delay, spanning from the fibre design optimization to the receiver memory dimensioning. First, the fibre refractive-index profile is optimized for low differential mode delay and low macro-bend losses. Afterwards, we present a semi-analytical model of the linear mode coupling induced by fibre imperfections and stress. Finally, the interplay between the linear mode coupling and the differential mode delay is studied numerically and analytically, allowing to quantify the receiver memory required for a given fibre span.
