Abstract

Epitaxial potassium niobate films have been deposited by metalorganic chemical vapor deposition (MOCVD). X-ray diffraction of the films deposited on (100) spinel substrates shows (110) and (001) reflections, indicating a multidomain structure. The electro-optic properties of the thin films were measured using a transmission technique. Effective electro-optic coefficients as large as 470 pm/V were observed. The observed electro-optic response was dominated by domain reorientation effects.
