Abstract

We report on the design and demonstration of holographic nanostructures via which the wavefront of light emanating from singular nanoscale emitters can be manipulated. Locating such a source within an engineered nanostructural environment enables the conversion of typically highly divergent and often spectrally broad radiation patterns into virtually any desired wavefront with controlled directionality, divergence and spectral composition (Fig. 1a).
