论文摘要
我们研究谐振器的自干扰效应，并在两个分离的端口处弯曲的波导。对于站立波和行进波谐振器的情况，这种干扰效应被证明是相似的，而在两个分离的谐振器的系统中，通过波导间接耦合，耦合形式和相关的干扰效果取决于选择哪种谐振器。由于自我干扰，可控制的光学响应，包括可调线宽和频移以及光学暗状态。此外，我们考虑了一个自我干扰光子 - 马格诺杂种模型，并显示了相关的类带状型线形状，该线形状在频率传感中具有潜在的应用。光子 - 磁通杂交不仅可以增强灵敏度并提供可调的工作区域，而且还可以依次对磁场强度进行光学读数。本文的结果为自我干扰效应及其潜在应用提供了更深入的了解。
We study the self interference effect of a resonator coupled with a bent waveguide at two separated ports. Such interference effects are shown to be similar for the cases of standing-wave and traveling-wave resonators, while in the system of two separated resonators indirectly coupled via a waveguide, the coupling forms and the related interference effects depend on which kind of resonators is chosen. Due to the self interference, controllable optical responses including tunable linewidth and frequency shift, and optical dark state can be achieved. Moreover, we consider a self-interference photon-magnon hybrid model and show phase-dependent Fano-like line shapes which have potential applications in frequency sensing. The photon-magnon hybridization can not only enhance the sensitivity and provide tunable working region, but also enables optical readout of the magnetic field strength in turn. The results in this paper provide a deeper insight into the self interference effect and its potential applications.
