  We fabricate an integrated photonic circuit with emitter, waveguide and
detector on one chip, based on a hybrid superconductor-semiconductor system. We
detect photoluminescence from self-assembled InGaAs quantum dots on-chip using
NbN superconducting nanowire single photon detectors. Using the fast temporal
response of these detectors we perform time-resolved studies of non-resonantly
excited quantum dots. By introducing a temporal filtering to the signal, we are
able to resonantly excite the quantum dot and detect its resonance uorescence
on-chip with the integrated superconducting single photon detector.
