A high-efficiency nanowire single-photon source

The project aims at engineering a nanowire-based single photon source (SPS) with efficiency approaching 100 % and takes place in close collaboration with the fabrication and characterization activities of an external partner. A recently discovered screening effect in highindex- contrast low-diameter nanowires will be exploited, an effect promising improved tolerance towards the fabrication-induced geometry imperfections currently limiting the efficiency of existing micropillar SPSs. The new nanowire physics will be analyzed, the established know-how will be used to suggest specific SPS structures for fabrication and several design-fabrication-characterization iterations will be performed.
