To achieve highly directional emission on a nanoscale, it is necessary to accurately control the optical phase over subwavelength distances. Here, we discuss several ways to establish such a control by utilizing propagating plasmons in metallic nanowires, material asymmetry in Ag-Au and Pd-Au dimers and hybrid sub- and super-radiant modes in ultracompact directional nanoantennas.
