以含氟自由基引发聚合MMA塑料光纤

Split step Finite Element Method for Calculating Optical Pulse Propagation in Optical Waveguide

本文介绍了以含氟自由基作为引发剂，引发聚合甲基丙烯酸甲酯（ＭＭＡ），并以此为纤芯材料制做塑料光纤。并从实验和理论上讨论了含氟自由基和一般引发剂引发聚合的聚甲基丙烯酸甲酯（ＰＭＭＡ）塑料光纤纤芯在化学结构上和光学衰减上的差异。

The split step finite element method (SSFEM) used to calculate optical pulse propagation in optical waveguide in time domain is proposed.The method is more stable and correct than the finite difference method (FDM).A large Z step can be used in this calculation.Some examples are given in this paper.
