摘要:

研究了均匀弱耦合多芯光纤(WC-MCFs)芯间串扰(IC-XT)解相关带宽的演化规律。采用四阶龙格-库塔法和复合辛普森积分法对修正的模式耦合方程进行数值求解。理论和数值计算表明,IC-XT的解相关带宽随传输距离的增加呈分数阶线性下降。实验进一步证实了IC-XT解相关带宽的演化规律,可作为信道模型的评价标准。最后,我们提出了一个新的通道模型与IC-XT的耦合矩阵自动生成的相位传递函数(PTF),这是很好地符合上述评估标准。我们相信,该信道模型可以提供一个很好的仿真平台,同质WC-MCF通信系统。

英文摘要:

We investigate the evolution of decorrelation bandwidth of inter core crosstalk (IC-XT) in homogeneous weakly coupled multicore fibers (WC-MCFs). The modified mode-coupled equations (MCEs) are numerically solved by combining the fourth order Runge-Kutta method and compound Simpson integral method. It can be theoretically and numerically observed that the decorrelation bandwidth of IC-XT decreases with transmission distance by fractional linear function. The evolution rule of IC-XT's decorrelation bandwidth is further confirmed by experiments, which can be used as an evaluation criterion for channel model. Finally, we propose a new channel model with the coupling matrix of IC-XT generated automatically by phase transfer function (PTF), which is in good agreement with the above evaluation criterion. We believe the proposed channel model can provide a good simulation platform for homogeneous WC-MCF based communication systems.
