Light Tunneling in Multi-Layered Plasmonic Crystals

In this work, we are demonstrating resonant light transmission through hybrid multi-layered plasmonic crystals, which are formed by a coupled nanohole and a nanoparticle array. This structures are shown to provide the conventional extraordinary optical transmission (EOT) peaks and also a newly found cavity-based mode is introduced with an emphasis to its high sensing capabilities. Plasmon hybridization in coaxial nanocavities is also addressed, where the nanohole array and the nanoparticle array are in the same layer.
