Abstract

Ferroelectric bismuth titanate thin films have been deposited on LaA103, SrTi03, MgO, Al2O3, and ZrO2/SiO2/Si substrates using a Q-switched Nd:YAG laser. X-ray diffraction studies show that most films on single crystal substrates have preferential crystallographic orientation. The film on MgO(11O) shows large electrooptic characteristics with an effective electrooptic coefficient of about 3.8xl0-15 m2/V2. Using a lens coupling method, it is demonstrated that light can propagate along the Bi4Ti3O12 layer in a Bi4Ti3O12/ZrO2/SiO2/Si(100) heterostructure.
