Parametric down-conversion (PDC) sources are known to be a robust and versatile tool for the generation of photon pair states. It has been demonstrated that by using nonlinear waveguides and engineering their properties, pulsed type II PDC sources are able to produce entangled states, which are both spatially and spectrally single-mode [1]. Additionally, the single-mode nature of the produced states allows their efficient use in continuous variable quantum information experiments.
We present the progress made towards realizing the detection of the noise properties of the generated photon pairs via homodyne detection and discuss technical challenges and the applied solutions.
