ABSTRACT
Heteroepitaxial Na0.5K0.5NbO3(1.5 μm)/La0.5Sr0.5CoO3(0.5 μm) (NKN/LSCO) films were grown on an Al2O3(011_2) single crystal (r-cut sapphire) by rf-magnetron sputtering (NKN) and pulsed laser deposition (LSCO) techniques. Prism coupling waveguide refractometry has been employed to characterize vertical capacitive electro-optical cells with 2×8 mm2 semitransparent Au top electrodes. Fitting reflectivity spectra to Fresnel formulas yields extraordinary and ordinary refractive indices ne=2.232 and no=2.234 as well as electro-optic coefficient r13=17.4 pm/V. Dispersion of the refraction index follows the Sellmeier formula n2=1+3.46/[1-(244 nm/λ)2] in the range from 400 nm to 850 nm.
