    介绍了一种用于半导体激光器-单模光纤耦合的圆锥端半球透镜的耦合效率的理论计算.失配不存在时,耦合效率随着锥长的增加而减小.失配存在时耦合效率随轴向和角向失配的增大而减小.

    The theoretical investigation of the coupling efficiency of a laser diode to a single mode fiber via a hemispherical lens on the tip of the tapered fiber in the presence of possible transverse offset and angular mismatch is reported.Without the misalignment,coupling efficiency increases with the decreasing of taper length.With the misalignment,this relation is that the coupling efficiency decreases with each kind of offset.
