Abstract

Chains and arrays of noncontacting noble-metal nanoparticles have remarkable optical properties associated with the excitation of surface plasmon polaritons—hybrid plasmonic-electromagnetic excitations of the overall structure. While considerable past interest has focused on guided waves by such structures, nanoparticle chains and arrays may also provide the basis of various other optical elements, such as lenses, as well as for vector-optical elements, in which the s- and p- polarized components of an incident optical field undergo markedly different processing in the transmission or reflection direction. These various applications of nanoparticle chains and arrays will be discussed with an emphasis on recent work on the generation of optical vector beams.
