High-Purity Telecom-Band Entangled Photon-Pairs via Four-Wave Mixing in Dispersion-Shifted Fiber
arXiv:quant-ph/0602034
Abstract
We have studied the purity of entangled photon-pairs generated in a dispersion-shifted fiber at various temperatures. Two-photon interference with visibility > 98% is observed at 77K, without subtraction of the background Raman photons.
