摘要
We reveal that there exists an indirect interaction between two single-mode microcavities which have no direct coupling. This indirect interaction is mediated by coupling the two microcavities to a common waveguide, and it plays a key role in obtaining the asymmetric Fano line shape of the transport spectrum of the coupled cavity system. Finally, we show that this sharp Fano line shape can contribute to highly sensitive sensing, which is immune to most environmental variations.
