Popis: Over the years, since the 1980s, various two photon interference experiments have been reported with photon pairs generated by parametric down conversion. Some of them have shown local interference features and non-local ones. An experiment is shown here which joins the two features at the same time in a Hong–Ou–Mandel interferometer. However, the non-local effects are lost if the photons’ arrival time difference at the beam splitter is much larger than the pulse length of the pump beam that generates the photon pair.
