Abstract

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.
