Stimulated emission tomography is a powerful and successful technique to both improve the resolution and experimentally simplify the task of determining the modal properties of biphotons. In the present manuscript we provide a theoretical description of SET valid for any quadratic coupling regime between a non-linear medium and pump ﬁelds generating photons by pairs. We use our results to obtain not only information about the associated modal function modulus but also its phase, for any mode…
