Abstract

Using the concept of leaky modes, we derive the minimum length of a single-mode fiber required to act as a spatial-mode filter of given quality. The degree of filter action is defined by the ratio of power carried by the fundamental mode to that carried by the leaky modes.

利用泄漏模式的概念，我们推导出了用作给定质量空间模式滤波器的单模光纤的最小长度。滤波器作用程度由基模携带的功率与泄漏模式携带的功率之比定义。
