Abstract:
|
Au nanoparticles deposited on a metallic film act as nanoantenna receivers and
transmitters for the coupling of free-space radiation into, and out of, 2D surface
plasmons. Nanosteps, sub-lO-nm gaps between metallic films of differing thickness, can
also launch and detect surface plasmons. In this thesis both types of structures are used to
locally launch propagating surface plasmon waves and probe their properties.
Nanoparticle-Iaunched surface plasmons emerge as two lobes of nominally 90 degree
angular width, propagating along the direction of incident polarization. Alternatively,
plasmons can be launched unidirectionally, by asymmetric illumination of a nanoparticle
receiver. |
