ABSTRACT

We review some recent experiments based upon multimode two-photon interference of photon pairs created by spontaneous parametric down-conversion. The new element provided by these experiments is the inclusion of the transverse spatial pro files of the pump, signal and idler fields. We discuss multimode Hong-Ou-Mandel interference, and show that the transverse profi le of the pump beam can be manipulated in order to control two-photon interference. We present the basic theory and experimental results as well as several applications to the field of quantum information.
