Plasmonic-Photonic Resonances in Low Contrast Hybrid Metallo-Dielecric Quasicrystals

摘要

We show the evidence of both plasmonic and photonic resonances excited in low contrast hybrid metallo-dielectric quasi-crystal (QC) nanostructures. By comparison with periodic crystal (PC) structures with the same filling factor, a richer spectrum of resonant modes may be excited. The resonances can be tuned via high refractive in-dex overlays and are sensible-to nanolayers of low refractive index materials (siO_2).
