Analyse du bruit lors de la génération de somme de fréquences dans les cristaux de niobate de lithium périodiquement polarisés (PPLN) et applications en régime de comptage de photons

Autor: Baudoin, Romain

Le processus de somme de fréquences optiques est utilisé dans certaines applications pour convertir des signaux de longueurs d’onde infrarouges vers le domaine de longueurs d’onde visibles. Cela permet de bénéficier de technologies plus perfo
