超微球透镜的耦合效率极限

Coupling efficiency limits of super-microball lens

本文从像差理论入手,分析了一种超微型透镜光学耦合系统的耦合理论问题,得出了可用作推算这种光学耦合系统耦合效率极限的计算公式。这组公式较Nicia导出的公式更具广泛的适用性,且可推广使用在一般透镜光纤耦合系统的分析之中。文中还给出了具体的计算实例和实验结果。

We analyse in this paper a class of optical coupling system consisting of super microball lens and multimode optical fibre by means of analysis of aberration of the system. A set of formulas which can be used for calculating the limits of coupling efficiency of the optical fibre coupling system are derived. These formulas are more applicable than those given by A. Nicia, and also can be used for analyses of other optical fibre coupling system. The calculating examples and experimental results are preserted.
