Abstract

The ability to control the directivity of light emission from single nanoscale emitters such as quantum dots or fluorescent molecules has made plasmonic nanoantennas one of the key elements in nanophotonics. Here we demonstrate that the wavefront of light emanating from such 'point sources' can be manipulated by locating them in a holographically designed nanostructured environment enabling the conversion of basic dipole radiation patterns into virtually any desired wavefront (e.g. a directional plane wave or an optical vortex beam).
