Abstract[English]
An electro-optic method and device fabricated with a metastable phase of BTO. The metastable tetragonal crystalline phase of BTO is preserved using direct wafer bonding on a thick SiO2 lower cladding layer for optical confinement in the active BTO.[French]
L'invention concerne un procédé et un dispositif électro-optiques fabriqués avec une phase métastable de BTO. La phase cristalline tétragonale métastable de BTO est conservée à l'aide d'une liaison directe de tranche sur une couche de gainage inférieure de SiO2 épaisse pour un confinement optique dans le BTO actif.
