Overview

The sources of the correlated photon pairs produce time/energy entangled photon pairs via the process of spontaneous parametric down conversion (SPDC). After creating photon pairs, the pump photons are removed from the output of the remaining pairs via a built-in set of optical filters. OZ Optics correlated pair sources come equipped with a stabilized pump laser along with pump power control via an internal variable optical attenuator. The SPDC medium is thermally stabilized to maintain ideal phase matching condition providing the highest photon conversion efficiency. The photon pairs are separated either by a wavelength splitter (WDM) or polarizing beam splitter (PBS) depending on the spectral bandwidth of the unit ordered.
