High efficiency entangled photon pair collection in type II parametric fluorescence
arXiv:quant-ph/0101074 · doi:10.1103/PhysRevA.64.023802
Abstract
We report on a method for optimizing the collection of entangled photon pairs in type-II parametric fluorescence. With this technique, we detected 360000 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%.
