We will present our recent progress in fabricating waveguide-integrated carbon nanotube light sources with superconducting single photon detectors [1]. This complete quantum photonic circuit allows for on-chip correlation experiments to explore non-classical light emission. We will furthermore explain how the photonic environment can be used to tailor the emission wavelength and linewidth of a nanotube emitter [2] and the feasibility of carbon nanotube transducers for fast signal processing [3].
