Abstract: Integrated photonics can greatly reduce the size, weight and power (SWaP) of optical assemblies, and also improve functionality and utility of quantum photonic sources and detectors, which may, in turn, benefit large-scale deployment and adoption of photonic devices for practical quantum communications and sensing. We report on good performance in entangled photon-pair generation using spontaneous four-wave mixing (SFWM) in silicon photonic micro-resonators, and using spontaneous parametric down-conversion (SPDC) in periodically-poled thin-film lithium niobate waveguides. We demonstrate gating and switching of single photons using integrated electro-optic modulators. Using superconducting nanowire single-photon detectors, we demonstrate capture of ultra-high bandwidth (>100 GHz) optical modulated signals at ultra-low received average power (below -100 dBm), a new milestone in optical oscilloscopy.
