Fluorescence imaging and spectroscopy is an important tool in many areas of research. Biology has particularly benefitted from fluorescence techniques, since a single molecule's position, local environment, and even activity can be studied in real time by tagging it with a fluorescent label. It is, therefore, important to be able to understand and manipulate fluorescence. One way to control fluorescence is to shape the local electromagnetic fields that excite the fluorescent molecule. This thesis studies the interaction between fluorescent molecules and two nanophotonic structures that highly modify local electromagnetic fields: the bowtie nanoantenna and the photonic crystal cavity. The study of plasmons, or coherent excitations of free electrons in a metal, has led to the fabrication of antennas at optical frequencies. In particular, gold bowtie nanoantennas have been shown to concentrate light from the diffraction limit at 800 nm (~300 nm) down to ~20 nm, while also enhancing the local electric field intensity by a factor of 1,000. This huge change in the local field greatly alters the absorption and fluorescence emission of nearby molecules. This thesis will show that the fluorescence from an initially-poor single-molecule emitter can be enhanced by a factor of 1,300, allowing for the measurement of one highly enhanced molecule over a background of 1,000 unenhanced molecules. By extending this experiment to molecules in solution, dynamics of single molecules in concentrated solutions can also be measured. While bowtie nanoantennas act to concentrate light, light does not remain in the structure for long. The photonic crystal cavity can be used to trap and store light, which has interesting implications for molecular emitters located nearby. This thesis will show that molecules can be lithographically positioned onto a photonic crystal cavity and that the molecule's fluorescence emission is coupled to the cavity modes.

The aim of this thesis consists in the study and modification of complex photonic nano-structures. Nowadays, propagation of light in such materials is a rich and fascinating area of research, both for its fundamental implications and for its practical technological impact. To deeply investigate light propagation inside these structures a high spatial resolution technique is required, especially because intriguing effects often occur on length scales comparable with the diffraction-limit or involve coupling phenomena on this length scale. For this reason in this thesis a Scanning Near-Field Optical Microscope represents one the most straightforward tool both to study and locally modify complex photonic nano-structures from perfect periodic to completely random ones.
