Promoting the coupling efficiency of waves by a 2d photonic crystal 利用二维光子晶体提高波的耦合效率
Fiber coupling efficiency 光纤耦合效率
Laser output power before fiber coupling according to the coupling efficiency 4 .客户可以依据光纤耦合效率来计算光纤耦合前激光器的
In order to improve coupling efficiency , the bottom - truncated and top - truncated are put forward ?提高耦合效率,提出了截底法和截顶法。
Without the misalignment , coupling efficiency increases with the decreasing of taper length 失配不存在时,耦合效率随著锥长的增加而减小。
With the misalignment , this relation is that the coupling efficiency decreases with each kind of offset 失配存在时耦合效率随轴向和角向失配的增大而减小。
The coupling efficiency can obtain 75 - 85 % at the wide working distance of 100 - 200um 这种方法的耦合效率在一定条件下可以在100 ? 200 m的工作距离上达到75 - 85 。
The coupling efficiency is simulated numerically . and the accuracy of the simulation is approved by our experiments 根据实验相关参数,对脉冲的展宽和压缩的实验设计的可行性进行了数值计算。
Considering the technics and coupling efficiency , optical fiber with sphere end is priority due to it ’ s simple technics and easy facture 从工艺和耦合效率两方面考虑,球透镜光纤的制作工艺简单、成熟且易于实现。
