“…Tailoring and controlling optical near-fields in plasmonic nanostructures facilitate the enhancement of numerous linear and nonlinear optical effects [45,50,51,52,53]. Applications are diverse and include surface enhanced Raman scattering [1,2], second [3,4] and third [5,6] harmonic generation, two-photon photoluminescence [59,60], continuum generation [61] or localized multiphoton photoemission [7,8].…”

“…The optimization of the evaporation conditions improved the surface roughness (measured by the root-mean-squared (RMS) value of the surface height) and enabled the fabrication of high quality nanoantennas. Plasmonic nanostructures offer unique possibilities for enhancing linear and nonlinear optical processes [45,50,51,52,53,6]. Recently, Kim et al [24] reported nanostructure-enhanced high harmonic generation (HHG).…”

“…Whereas harmonic linewidths are influenced by the spectral amplitude and temporal duration of the fundamental driving field, the linewidths of atomic and ionic fluorescence are governed by the spontaneous lifetime. If harmonic radiation were present, we would expect several linewidths to be broader, given the incident pulse duration and known properties of plasmonic resonances [45,51,6]. …”

“…The main problem in this respect is caused by the lack of suitable probes for sensing the nanoscopically confined near-fields. Whereas other properties, for example, the plasmonic resonances of nanoantennas are relatively easy to access via spectroscopy [52,51,16] (see also the dark-field scattering spectra in Fig. 3.2e), the absolute intensity values of local fields are still difficult to extract.…”

The present (cumulative) thesis examines fundamentals of nanostructure-enhanced extreme-ultraviolet light generation in noble gases using two different nanostructure geometries for local field-enhancement. Specifically, resonant antennas and tapered hollow waveguide nanostructures are utilized to enhance low-energy femtosecond laser pulses, which in turn induce light emission from excited xenon, argon and neon atoms and ions. Spectral analysis of this radiation reveals that coherent high-order harmonic generation is not feasible under the examined conditions, contrary to former expectations and reports. Instead, the spectral characteristics unequivocally identify that incoherent fluorescence from multiphoton excited and strong-field ionized gas atoms is the predominant process in such schemes. Furthermore, novel nanostructure-enhanced effects are reported such as surface-enhanced fifth-order harmonic generation (from bow-tie nanoantennas) and the formation of a bistable nanoplasma (in a hollow waveguide). These effects offer intriguing links between nonlinear nano-optics, plasma dynamics and extreme-ultraviolet radiation.v vi

“…Therefore, exploring the links between them can have a great significance in optimizing the antenna structure. Most theoretical studies on the bowtie antenna have focused on the gap distance [24,25]. However, the performance of the bowtie nano-antenna can be affected by the size, shape, gap distance, and the incident wavelength.…”

Abstract-With the development of nano-optic technology, the optical nano-antenna has been widely used in the fields of novel light sources, high-sensitive biological sensors, nanometer lithography, and nano-optical imaging. The relationship between the structural parameters of the antenna and the Purcell factor is very important for engineering applications. The electric near field profile of the antenna was calculated and analyzed by using the finite-difference time-domain (FDTD) method, and the influence of the structural parameters on the Purcell factor and the electric field was thoroughly investigated. A careful comparison of bowtie antenna radiation characteristics with different structural parameters was carried out. The results show that the thickness, the length and the curvature radius have great effects on the Purcell factor and the optical antenna's electric near field. These findings are promising for improving the performance of the optical bowtie nano-antenna.

Recent advances in the chemistry of colloidal semiconductor nanocrystal doping have led to new materials showing fascinating physical properties of potential technological importance. This article provides an overview of efforts to dope one of the most widely studied colloidal semiconductor nanocrystal systems, CdSe quantum dots, with one of the most widely studied transition‐metal dopant ions, Mn2+, and describes the major new physical properties that have emerged following successful synthesis of this material. These properties include spin‐polarizable excitonic photoluminescence, magnetic circular dichroism, exciton storage, and excitonic magnetic polaron formation. A brief survey of parallel advances in the characterization of analogous self‐assembled Mn2+‐doped quantum dots grown by molecular beam epitaxy is also presented, and the physical properties of the colloidal quantum dots are shown to compare favorably with those of the self‐assembled quantum dots. The rich variety of physical properties displayed by colloidal Mn2+‐doped CdSe quantum dots highlights the attractiveness of this material for future fundamental and applied research.
