Luminescence-induced noise in single photon sources based on BBO crystals
Luminescence-induced noise in single photon sources based on BBO crystals
Single-photon sources based on the process of spontaneous parametric down-conversion play a key role in various applied disciplines of quantum optics. We characterize intrinsic luminescence of BBO crystals as a source of non-removable noise in quantum-optics experiments. By analysing its spectral and temporal properties together with its intensity, we evaluate …
