In this paper, we discuss the Fano response from a hybrid trimer composed of gold and silicon nanospheres. This allows the structure to exhibit plasmonic properties while having a versatile spectral tuning of its Fano response. We analyze the Fano response from the point of view of the individual subsystem as well as the coupling of supermodes of the structure. The coupling between the sustained non-orthogonal eigenmodes can be traced as a result of these modes sharing the same multipolar moments. With this, we provide insight into designing a hybrid structure with tunable Fano properties.

具有不对称介电常数的三聚物结构中Fano响应的出现

在本文中，我们讨论了由金和硅纳米球组成的混合三聚体的Fano响应。这使得该结构具有等离子体特性，同时对其Fano响应具有通用的光谱调整能力。我们从各个子系统以及结构超模耦合的角度分析Fano响应。由于这些模式共享相同的多极矩，因此可以追踪持续的非正交本征模式之间的耦合。这样，我们就可以洞悉设计具有可调Fano属性的混合结构。
