Plasmon resonant arrays or meta-surfaces shape optical fields and the local density of states. They provide large regions of enhanced emission from emitters and greater design flexibility than single nanoantennas. This makes them of great interest for engineering optical absorption and emission. Here we study the coupling of single self-assembled semiconductor quantum dots to plasmonic meta-surfaces. We investigate the influence of spectral properties of the nanoantenna array and the position of the emitter in the unit cell of the structure. We observe a resonant enhancement due to emitter-array coupling in the far-field regime and find a clear difference from the interaction of an emitter with a single antenna.
