In this work we report the results of the experimental investigation of the refractive index change due to the photorefractive effect in periodically poled lithium niobate (PPLN) Ti-diffused waveguides in dependence on light intensity and sample temperature. We show an experimental method that allows for the direct determination of the refractive index change. The saturation state of the change of the refractive index is reached at 775 nm with input power of 50 μW.
