Photon-triplets for quantum optics generated by a phase-matched third-order difference-frequency mixing in a KTiOPO4 bulk crystal pumped at 532 nm
Gaspar Mougin-Trichon, Veronique Boutou, Corinne Felix +2
We report implementation and modelling of an efficient photon-triplets generation experiment based on a difference-frequency-mixing of two picosecond beams at 532 nm and 1491 nm in…

Criteria on quantum fluctuations of vacuum and photons influence in Spontaneous-Parametric Down-Conversion and Four-Wave-Mixing
Benoît Boulanger, Gaspar Mougin-Trichon, Véronique Boutou
This article is a theoretical and quantitative exploration of the limit regarding the pump intensity between the two regimes of spontaneous-parametric down-conversion (SPDC) as wel…

Semi-classical modelling of second-order spontaneous down-conversion measured over 10 decades of pump intensity in a type II phase-matched KTP crystal
Julien Bertrand, Véronique Boutou, Benoît Boulanger
We performed a second-order spontaneous parametric down-conversion (SPDC) experiment in a Type II phase-matched KTiOPO4 crystal pumped at 532 nm giving birth to a signal beam at 10…
