Plasmons can be excited by inelastic tunneling of electrons [1,2]. This provides a broadband source of plasmons that can be integrated into plasmonic nanocircuitry. The emission wavelength and bandwidth can be controlled via plasmonic resonances which enhance the inelastic tunneling process.
Here we present an electrically-driven multi-element Yagi-Uda antenna that emits light into one specific direction [3]. Furthermore, we discuss mode-specific electric excitation of plasmons in a two-wire transmission line and its application towards polarization-controlled nano-light sources.
