斜端面光纤耦合效率理论与实验研究
Theoretical and experimental study on coupling efficiency of LD at different fiber inclined surface
-
摘要: 应用场耦合方法模拟计算了不同光纤斜端面角度下半导体激光器的耦合效率,并进行了实验测量.结果表明,不同的光纤斜端面角度下,对半导体激光器的耦合效率影响很大,根据不同的芯片参数合理选择不同的斜端面光纤可以得到尽可能高的耦合效率.Abstract: Using field coupling theory,the coupling efficiency of LD at different fiber inclined surface is discussed,and experimental results are presented too.The results show that the coupling efficiency is affected obviously by the fiber inclined angle,which can be improved if we choose the angle properly.
