摘要：

We report experimental characterization of DC electro-optic coefficients r(13), r(23) and r(33) in thin film single crystalline BaTiO3 on DyScO3. The epitaxial BaTiO3 thin film is sandwiched between a SrRuO3 bottom electrode and an indium tin oxide (ITO) top electrode. We characterize the DC electro-optic coefficients r(13), r(23), and r(33 )by the prism coupling method at 636.6 nm for the BaTiO3 thin film. The results show the DC coefficients r(13) = 4.2 pm/V, r(23) = 4.6 pm/V and r(33) = 9.0 pm/V. (C) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
