A Parametric down-conversion (PDC) source is known to be a robust and versatile tool for the generation of states of photon pairs. It has recently been demonstrated that waveguide-embedded PDC sources are able to produce highly indistinguishable and pure photon pairs. In a continuous-variable picture, this corresponds to a single two-mode squeezed state. As a benchmark for future experiments, we record the attainable single-mode squeezing and analyze the remaining state impurities to characterize the extractable squeezing.
