Phys. Rev. A 64, 023802 (2001) [4 pages]High-efficiency entangled photon pair collection in type-II parametric fluorescenceReceived 19 December 2000; published 2 July 2001 We report on a method for optimizing the collection of entangled photon pairs in type-II parametric fluorescence. With this technique, we detected 360 000 polarization-entangled photon pairs per second in the near-ir region in single-mode optical fibers. The entanglement of the photon pairs was verified by measuring polarization correlations in different bases of at least 96%. © 2001 The American Physical Society URL:
