    "abstract": "An analytical calculation of the interaction geometry of two interlinked\nsecond-order nonlinear processes fulfilling phase-matching conditions is\npresented. The method is developed for type-I uniaxial crystals and gives the\npositions on a screen beyond the crystal of the entangled triplets generated by\nthe interactions. The analytical results are compared to experiments realized\nin the macroscopic regime. Preliminary tests to identify the triplets are also\nperformed based on intensity correlations.",
