    "abstract": "We report on a new kind of correlated photon-pair source based on a waveguide\nintegrated on a Periodically Poled Lithium Niobate substrate. Using a pump\nlaser of a few micro-Watts at 657 nm, we generate degenerate photon-pairs at\n1314 nm. Detecting about 1500 coincidences per second, we can infer a\nconversion rate of 10-6 pairs per pump photon, which is four orders of\nmagnitude higher than that obtained with previous bulk sources. These results\nare very promising for the realization of sources for quantum communication and\nquantum metrology experiments requiring a high signal-to-noise ratio or working\nwith more than one photon-pair at a time.",
