Abstract

Ba_0.6Sr_0.4TiO₃ thin film was deposited on MgO(001) substrate using pulsed laser deposition. On appropriate film-growing conditions, the thin film was highly oriented along the (001) direction. Electric field dependence of birefringence of the thin film was measured using Sernamont method. The electro-optic coefficient resulted in 1 × 10^-15 m²/V², which means one of the best electro-optic performance in dielectric thin films. It is interesting that Ba_0.6Sr_0.4TiO₃ thin film is highly electrooptic as well as highly tunable in microwave frequency. Optical applications of Ba_0.6Sr_0.4TiO₃ thin film such as electro-optic modulators and optical waveguides are expected.
