我们基于时间耦合模式理论分析了驻波 (SW) 或行波 (TW) 类型的两个耦合相同腔的传输特性。对于直接（腔-腔）和间接（腔-波导-腔）耦合腔系统都观察到模式分裂。直接耦合和间接耦合的影响如果共存于一个系统中，可以相互抵消，从而不会发生模式分裂，并且保留原始的单腔谐振频率。通过调整耦合腔系统的配置，可以获得不同的传输光谱特性，包括传输分裂、零传输、Fano型传输、类电磁感应透明（EIT）传输和类电磁感应吸收（EIA）传输。有趣的是，侧耦合 SW 腔系统的性能与欠耦合 TW 腔类似。这些结果对于设计用于集成纳米光子学的基于腔的器件非常有用。 (C) 2010 美国光学学会
We analyze transmission characteristics of two coupled identical cavities, of either standing-wave (SW) or traveling-wave (TW) type, based on temporal coupled mode theory. Mode splitting is observed for both directly (cavity-cavity) and indirectly (cavity-waveguide-cavity) coupled cavity systems. The effects of direct and indirect couplings, if coexisting in one system, can offset each other such that no mode splitting occurs and the original single-cavity resonant frequency is retained. By tuning the configuration of the coupled cavity system, one can obtain different characteristics in transmission spectra, including splitting in transmission, zero transmission, Fano-type transmission, electromagnetically-induced-transparency (EIT)-like transmission, and electromagnetically-induced-absorption (EIA)-like transmission. It is also interesting to notice that a side-coupled SW cavity system performs similarly to an under-coupled TW cavity. The results are useful for the design of cavity-based devices for integration in nanophotonics. (C) 2010 Optical Society of America
