空分复用技术已成为解决未来长距离光传输系统容量不足的有效途径。在本文中，我们提出了一种分析方法来计算在多模光纤SDM系统的不同光纤模式中传播的信号之间的非线性干涉。我们讨论了几个简化的模内和模间四波混频理论的基础上，并比较分析模型与模拟在一个示例性的少模光纤传输系统与三个和六个空间模式。为了深入了解模态间非线性信号失真的影响，我们将重点放在模态内和模态间非线性的相对强度上。分析模型和数值模拟之间的一个很好的协议被发现，使该模型成为一个易于使用的工具来估计整体的非线性失真的空分复用传输系统与多模光纤。
Space-division multiplex has become a promising approach to overcome future capacity shortages in long-haul optical transmission systems. In this paper, we present an analytical approach to calculate the nonlinear interference between signals that travel in different fiber modes of a multimode fiber SDM system. We discuss several simplifications based on intra- and intermodal four-wave mixing theories, and compare the analytical model with simulations in an exemplary few-mode fiber transmission system with three and six spatial modes. To generate a deep understanding of the impact of intermodal nonlinear signal distortions, we focus our analysis on the relative strength of intra- and intermodal nonlinearities. A good agreement between the analytical model and numerical simulations is found, making the model an easy-to-use tool to estimate the overall nonlinear distortion in space-division multiplexed transmission systems with multimode fibers.
