Abstract

We report extensive numerical studies on plasmonic dimers of different configurations and find that their coupling effects can be categorized into three types of phenomena. First, like ordinary mechanical systems, the plasmonic dimers can exhibit positive couplings that show anti-crossing behavior. Second, they can also be arranged to exhibit negative couplings that display opposite trends in resonant frequency shifts. Third, when there are surface currents in proximity to each other, the resonance frequencies of the dimers exhibit unusual redshifts that do not have any analogies in conventional systems. Our work suggests that in addition to the well-known electric and magnetic dipolar interactions, contributions from the inductance of displacement currents in the near field cannot be ignored. Overall, asymmetric plasmonic dimers exhibit better sensitivities than the symmetric counterparts and our extensive studies also enable us to identify the plasmonic dimer with the highest sensing capabilities.

Figures (4)

Fig. 1
Fig. 1

Coupling diagrams of asymmetric metamolecules. Despite the diverse structural variations, our extensive numerical simulations reveal that there are only three types of couplings in metamolecules consisting of two meta-atoms. The coupling phenomena can be categorized into (a) type I (positive couplings), (b) type II (negative couplings), and (c) type III (two redshifts), respectively. The arrows denote the polarization of the normally incident light.

Fig. 2
Fig. 2

Simulated resonant frequency shifts with respective to distances between two meta-atoms for three representative metamolecules in each type of couplings. The arrows denote the polarization of the normally incident light. The dashed lines are fitting results using solutions of Eq. (2).

Fig. 3
Fig. 3

Transitions from type II coupling to type III coupling as the distance between meta-atoms decreases. The figures in the right display three metamolecules that exhibit the transition. The arrows denote the polarization of the normally incident light.

Fig. 4

Resonant frequency sensitivity vs. distance between meta-atoms for four representative metamolecules chosen from type I (black and red lines) and type III (blue and green lines) couplings (type II couplings are only observed at large distances).
