磁振子介导的光子-光子耦合中耦合诱导透明与透射信号吸收的共存
Coexistence of coupling-induced transparency and absorption of transmission signals in magnon-mediated photon-photon coupling
摘要：
在由钇铁石榴石（YIG）薄膜和三个同心倒开口环谐振器（ISRR）组成的平面混合结构中，实验确定了磁振子介导的光子-光子耦合中耦合诱导透明（CIT）和信号吸收（CIA）的共存。实验观察到的同时CIT和CIA现象归因于磁振子介导的光子-光子耦合之间的独立去耦ISRR。为了捕捉所观察到的相互作用的一般物理，我们构建了一个适当的分析模型的基础上的一致性和耗散的多路径相互作用之间的平衡，该模型精确地再现了CIT和CIA实验观察到从一个单一的混合系统。这项工作有望为设计高效，灵活和可控性良好的光子-磁振子器件提供指导，这些器件对目前正在开发的量子技术的应用具有很高的需求。
英文摘要：
Coexistence of coupling-induced transparency (CIT) and absorption (CIA) of signals in magnon-mediated photon-photon coupling was experimentally determined in a planar hybrid structure consisting of a yttrium iron garnet (YIG) film and three concentric inverted-split-ring resonators (ISRRs). The experimental observation of simultaneous CIT and CIA phenomena was ascribed to magnon-mediated photon-photon coupling between the individually decoupled ISRRs. In order to capture the generic physics of the observed interactions, we constructed an appropriate analytical model based on the balance between the coherent and dissipative multiple-paths interactions, which model precisely reproduced both the CIT and CIA experimentally observed from a single hybrid system. This work, promisingly, can provide guidance for design of efficient, flexible, and well-controllable photon-magnonic devices that are highly in demand for applications to quantum technologies currently under development.
