Abstract

Monitoring of electrical field poling processes by optical polarimetry (EFPOP) is presented as a simple alternative method for the study of induced noncentrosymmetry, related to nonlinear optical second-order effects in organic chromophore-doped sol-gel films. Dynamics of EFPOP has been closely followed in guest-host systems, consisting of porous sol-gel silicate film matrices doped with p-nitroaniline, as evidence of the EFPOP sensitivity to chromophore orientational order.
