摘要

We report on the measurement of the Kerr electro-optic susceptibility in DPOP-poly-phenylene-vinylene films sandwiched between indium tin oxide and metal electrodes. Such a polymer was designed and used for the application in third-order non-linear optical integrated devices. The results, obtained by means of non-linear reflectance ellip- sometry, indicate the presence of charge injected and trapped in the polymer films under application of a dc voltage. The values of the Kerr X~(3) susceptibility and of the total voltage drop on the film are evaluated.
