In the last 10 years BaxSr1-xTiO3
(BST-x) has been the subject of many investigations, almost all focused
on radio-frequency applications for wireless telecommunications. Nowadays,
BST is the most promising candidate for tunable microwave filter applications.
These promising dielectric properties motivate us to investigate the electro-optic
characteristics of this material. A large number of ferroelectric oxide
films have already been studied as candidates for electro-optic applications,
Nevertheless, very few studies deal with the electro-optic properties
of BST.
My work focuses on the synthesis of BST films by pulsed laser deposition
(PLD) and the exploration of their electro-optic properties. If promising
properties are found on the BST material, its integration in actual optical
device, as a waveguide or tunable filter, will be pursued. Also, the study
of Er-doped BST films could be very interesting for optoelectronics. The
main aim of the thesis is to investigate the actual effectiveness of BST
as electro-optic candidate, and consequently, to integrate BST in real
integrated optical devices.
