A down-conversion source of positively spectrally correlated and decorrelated telecom photon pairs

We experimentally characterize a spontaneous parametric down-conversion source, based on a Beta-Barium-Borate crystal capable of emitting photons with positive or no spectral correlations. Our system employs a carefully designed detection method exploiting two InGaAs detectors.
