    "abstract": "We report on a method for optimizing the collection of entangled photon pairs\nin type-II parametric fluorescence. With this technique, we detected 360000\npolarization-entangled photon pairs per second in the near-IR region in\nsingle-mode optical fibers. The entanglement of the photon pairs was verified\nby measuring polarization correlations in different bases of at least 96%.",
