  abstract =     "Engineering and controlling well-defined states of light for quantum information
                 applications is of increasing importance as the complexity of quantum systems
                 grows. For example, in quantum networks, high multi-photon interference visibility
                 requires properly devised pure photon sources. In this paper, we present a
                 theoretical model for a spontaneous parametric down conversion source based on an
                 integrated cavity-waveguide, where single narrow-band, possibly distinct, resonant
                 modes for the idler and the signal fields can be generated. This mode selection
                 takes advantage of the clustering effect, due to the intrinsic dispersion of the
                 nonlinear material. We show that, by engineering the clustering effect in an
                 integrated cavity-waveguide and by using a standard detector, one can efficiently
                 generate heralded pure single photons even with a continuous-wave pumping mode. The
                 photon source proposed in this paper is extremely flexible and could easily be
                 adapted to a wide variety of wavelengths and applications, such as long-distance
                 quantum communication.",
