Plasmon-coupled tip-enhanced near-field optical microscopy.
Near the cut-off radius of a guided waveguide mode of a metal-coated glass fibre tip it is possible to couple radiation to surface plasmons propagating on the outside surface of the metal coating. These surface plasmons converge toward the apex of the tip and interfere constructively for particular polarization states of the initial waveguide mode. Calculations show that a radially polarized wa...
متن کاملRobust subnanometric plasmon ruler by rescaling of the nonlocal optical response.
We present the optical response of two interacting metallic nanowires calculated for separation distances down to angstrom range. State-of-the-art local and nonlocal approaches are compared with full quantum time-dependent density functional theory calculations that give an exact account of nonlocal and tunneling effects. We find that the quantum results are equivalent to those from classical a...
متن کاملNear-Field Optical Microscopy of Surface Plasmon Polaritons Nano-Optics
Near field optical microscopy techniques can be employed to characterize surface plasmon polaritons phenomena. These studies have set the stage for the current surge in the nano-optics field. In this chapter experiments and numerical developments conducted to the understanding of this area are outlined. Furthemore a scanning near-field microwave microscope is presented as an alternative techniq...
متن کاملImaging slit-coupled surface plasmon polaritons using conventional optical microscopy.
We develop a technique that now enables surface plasmon polaritons (SPPs) coupled by nano-patterned slits in a metal film to be detected using conventional optical microscopy with standard objective lenses. The crux of this method is an ultra-thin polymer layer on the metal surface, whose thickness can be varied over a nanoscale range to enable controllable tuning of the SPP momentum. At an opt...
متن کاملInitial and Plasmon-Enhanced Optical Properties of Nanostructured Silicon Carbide
Nanostructured silicon carbide (SiC) is considered today as a good alternative to the conventional materials for various multidisciplinary applications. In this thesis, SiC nanostructures were elaborated by means of electrochemical etching and laser ablation techniques. The first part of the thesis clarifies size-dependence of optical properties as well as importance of local-field effects onto...
