Abstract
This article focuses on the optical properties of two complementary families of metallic nanostructured systems supporting plasmonic excitations. These are surface plasmon polaritonic crystals and arrays of aligned metallic nanorods. These structures can be thought of as originating from two generic geometries: surface plasmonic crystals are made from a continuous metal film, nanostructured with a dielectric material while preserving the film’s continuity. The complementary nanorod structure is created from an assembly of metal nanoparticles embedded in a dielectric host. As a result, the optical properties of plasmonic crystals stem from propagating surface plasmons polariton modes, while the eigenmodes supported by arrays of nanorods originate from localized surface plasmons. Both types of structures demonstrate unique optical properties governed by theses fundamental resonances, which prove remarkable in the development of nanophotonic devices including active functionalities where optical signals are controlled by light or other external electric or magnetic field stimuli. A common advantage of these two types of systems rests on the possibility to finely tune their geometry in order to design their optical response with tailored dispersion and electromagnetic field distribution. In this context, this Chapter describes ‘design’ principles and applications of metallic nanostructures for achieving a desired and dynamically controllable photonic response. This optical response is analyzed in the far-field (Fraunhofer) region and will be discussed on the basis of the near-field optical interactions from which they originate.
