■ Abstract : Plasmonic nanostructures that act as optical nano-antennas for visible light offer interesting opportunities for locally concentrating and enhancing the electric field of an incident light wave, or of spectrally tuning the antenna characteristics via the size, shape and material. By combining the antenna structures with a second component in hybrid configurations, such as quantum dots, fluorescent molecules, or organic thin-films, the antennas can be employed to modify the absorption and emission characteristics of these objects in the coupled system. Key challenges in this context are the optimization of the antenna properties in view of the envisaged application, as well as achieving selective coupling of the nano-emitters to the high near-field regions of individual antennas.

In this presentation the Eberhard Karls University Tübingen in Germany and its Core Facility, the Center for Light-Matter-Interaction, Sensors and Analytics (LISA+) will shortly be introduced. The top-down nanofabrication of optical nano-antennas by various nano-lithographic techniques, combined with etch-mask transfer, will be demonstrated. Their linear and nonlinear optical properties are investigated. Conical nanoantennas offer narrow, high near-field intensity hotspots near their tip apexes. Procedures for selectively coupling few or single nano-emitters to these tips will be shown. Applications of different hybrid antenna configurations for absorption or emission enhancement, lifetime reduction, and biosensing through plasmon resonance shifts in a microfluidic environment will be illustrated.
