Plasmonic Dispersion Relations and Intensity Enhancement of Metal–Insulator–Metal Nanodisks

[Image: see text] We show that the plasmon modes of vertically stacked Ag–SiO(2)–Ag nanodisks can be understood and classified as hybridized surface and edge modes. We describe their universal dispersion relations and demonstrate that coupling-induced spectral shifts are significantly stronger for s...

description [Image: see text] We show that the plasmon modes of vertically stacked Ag–SiO(2)–Ag nanodisks can be understood and classified as hybridized surface and edge modes. We describe their universal dispersion relations and demonstrate that coupling-induced spectral shifts are significantly stronger for surface modes than for edge modes. The experimental data correspond well to numerical simulations. In addition, we estimate optical intensity enhancements of the stacked nanodisks in the range of 1000.
