摘要:
In this paper, we present an analysis of single-mode fiber resonators with 2 x 2 directional single-mode couplers, using signal flow graphs. Our method is more simple than conventional methods. Furthermore, a novel compound fiber resonator constructed by two cross-coupling fiber resonators, which is shown to be useful for line narrowing in fiber lasers, is investigated.
