In order to develop a novel ring resonator optical switch, we have studied the structural and optical properties of the electrooptic material (Ba,Sr)TiO3 (BST) deposited by RF sputtering on a SiO2 cladding layer (1.0 μm). The crystallinity of the BST films is evaluated by X-ray diffraction and the optical propagation loss of the waveguides is measured using a He-Ne laser. As a result, it is found that there is a strong relationship between the optical propagation loss and crystallinity of the sputtered film. It is suggested that the propagating light is influenced by the crystal property, for example, the grain size and density of the polycrystalling BST film.
