Le développement croissant des réseaux de télécommunication de fibre optiques nécessite la mise au point de systèmes optiques intégrés (amplificateurs, switch optique, WDM, DWDM, ...). La découverte de génération de second harmonique dans les verres ouvre de nouvelles perspectives d'application dans le domaine des télécoms. C'est dans ce contexte que nous avons débuté cette thèse par la recherche de nouveaux systèmes vitreux (Nb2O5 – P2O5 – CaO – B2O3 et TeO2 – PbO – P2O5), qui après un traitement de poling présentent une forte susceptibilité non linéaire d'ordre deux. L'étude a porté sur la synthèse, le traitement de poling et les caractérisations physico-chimiques (structurales et optiques) des verres. Une application aux couches minces a...
