This research cooperation aims to work towards the realization of integrated semiconductor quantum optical circuits that combine on-chip quantum dot single photon sources, passive photonic crystal optical elements (cavities, waveguides, beam splitters) and on-chip single photon detection. To achieve this the participating groups at TUM and Stanford will pool expertise in the development of NbN superconducting nanowire single photon detectors (SSPD) on GaAs photonic crystal quantum optical circuits containing semiconductor quantum dots. SSPD technologies offers many advantages including small size, high quantum efficiency, high timing resolution, low dark counts and wide wavelength coverage. The general feasibility of the hybrid NbN/GaAs technology has been established in the TUM group but requires study to integrate with the photonic crystal hardware developed in both Stanford and TUM groups. Both linear optics circuits and functionality enabled by the non-linear properties of III-V systems will be addressed.
