richard taubert FROM NEAR-FIELD TO FAR-FIELD: plasmonic coupling in three-dimensional nanostructures From Near-Field to Far-Field: Plasmonic Coupling in Three-Dimensional Nanostructures
This thesis provides a comprehensive study of the coupling phenomena that occur in plasmonic nanostructures. Electromagnetic coupling between metallic nanoparticles leads to strong spectral modifications in the structures, which are determined using linear optical spectroscopy in the visible and infrared wavelength range. In contrast to previous investigations, the key aspect here are the prope...
متن کاملTerahertz near-field vectorial imaging of subwavelength apertures and aperture arrays.
We present measurements of the complete terahertz (THz) electric near-field distribution, E(x), E(y) and E(z), in both the time- and frequency-domains, for subwavelength apertures and subsections of subwavelength aperture arrays. Measuring the individual components of the THz near-field with subwavelength spatial resolution, as they emerge from these structures, illustrates how the field intera...
متن کاملNear- and far-field model coupling methodology for wastewater discharges
The prediction of pollutant concentrations in the coastal waters is essential for water quality control. The description of physical processes and their implementation in computer models shows that there is neither a “complete model” including all important spatial and temporal scales of the dominant processes nor a standard procedure for the coupling of models. This is explained by deficiencie...
متن کاملNear-field strong coupling of single quantum dots
Strong coupling and the resultant mixing of light and matter states is an important asset for future quantum technologies. We demonstrate deterministic room temperature strong coupling of a mesoscopic colloidal quantum dot to a plasmonic nanoresonator at the apex of a scanning probe. Enormous Rabi splittings of up to 110 meV are accomplished by nanometer-precise positioning of the quantum dot w...
متن کاملNear-field distribution in light-coupling masks for contact lithography
We discuss the potential and limitations of light-coupling masks for high-resolution subwavelength optical lithography. Using a three-dimensional fully vectorial numerical approach based on Green’s tensor technique, the near-field distribution of the electric field in the photoresist is calculated. We study the dependence of the illuminating light and the angle of incidence on polarization. Fur...
