Enhancement of electro-optic response in BaTiO3 films integrated on Si via heating and cooling rate control

Abstract Recent advancements in BaTiO3-based Si-integrated photonics devices have shown very large electro-optic responses, allowing for aggressive device scaling in both size and power. However, control of the crystallographic domain structure of high-quality epitaxial BaTiO3 films still remains a...
