Abstract

Summary form only given. Using the variable-frequency ellipsometric technique, we measure the total refractive index modulation as a function of the frequency of the applied electric field. From these measurements we deduce the relative contributions of the poling birefringence, the Pockels, and the Kerr effects. The experimental setup for the variable frequency ellipsometric technique is presented. We show experimental data for two high-diffraction efficiency photorefractive polymer composites, DMNPAA:PVK:ECZ:TNF and FDEANST:PVK:ECZ:TNF.
