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 ellipsometry, indicate the presence of charge injected and trapped in the polymer films under application of a dc voltage. The values of the Kerr χ(3) susceptibility and of the total voltage drop on the film are evaluated.

Abstract
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 ellipsometry, indicate the presence of charge injected and trapped in the polymer films under application of a dc voltage. The values of the Kerr χ(3) susceptibility and of the total voltage drop on the film are evaluated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
