Abstract given by the source: This proposal is aimed at greatly simplifying and diversifying means to generate light on a nanoscale by combining quantum emitters with hybrid optical nanoantennas. The core of the project is focused on three specific goals - efficient single-photon sources, strongly coupled systems and bright fluorescent markers. The proposal therefore addresses three main parameters affecting the quality of the quantum emitters - quantum yield, energy level spacing and direction of light emission. Efficient nanoscopic light sources are important in many areas of science ranging from quantum optics, quantum information processing and optical computing to fluorescence microscopy and bio-imaging. The goals of the proposal are going to be addressed with optical antennas. In contrast to the radiowave counterparts, where resonances are of geometrical nature, optical antennas support surface charge oscillations, with resonance conditions depending on size, shape, electromagnetic environment and "material" of which the antenna is made of. Thus, breaking antennas compositional symmetry may significantly enrich possible antennas design and facilitate manipulation of their material-specific electrical-, surface-, chemical-, magnetic-, etc. properties to provide a whole family of novel nanodevices. Furthermore, asymmetric antennas possess unusual optical response, such as color splitting, due to ´built-in´ optical phase mismatch, which well suits the goal to increase efficiency of quantum emitters.
