Optical Interaction in a Plasmonic Metallic Nanoparticle Chain Coupled to a Metallic Film

Abstract:

We demonstrated the coupling of localized surface plasmons and surface plasmon polaritons modes in a system composed of a metallic particle chain separated from a thin metallic film. The results showed that: (1) the thickness of the metallic particles buried in the dielectric space, (2) the positions of the particles influence the level of interaction between localized surface plasmons and surface plasmon polaritons modes. Meanwhile, the positions of the particles and the thickness of the metallic particles control the electromagnetic enhancement and influence the electric field distributions in this system. This kind of system has a very promising candidate for biosensing and surface enhanced spectroscopy applications.
