Controlling the dispersion and directionality of the emission of nanosources is one of the major goals of Nanophotonics. In this presentation, we will discuss how this control can be achieved with subwavelength structures, known as nanoantennas, of defined shape and dimensions. The precise bottom-up nanofabrication of these structures allows to strengthen the near- and far-field coupling of resonances, which define the light emission of sources in their proximity.
