摘要
利用显式有限差分法数值解阶跃多模光纤的功率流方程 ;研究阶跃塑料光纤中不同入射光束的模式耦合模式及模式耦合引起的衰减 ;得出塑料光纤达到模均衡分布的模式耦合长度是 2 0
A theoretical investigation on the mode coupling and mode coupling induced attenuation in step index plastic optical fiber under different launching condition,solved numerically power flow equation of multimode optical fiber by explicit finite difference methods,and obtained coupling length of plastic optical fiber is about 20 m.
