Abstract
Electro-optical (EO) coefficients are determined for two dye/polymer guest-host systems as a function of the electric field, temperature, and concentration. Above the glass transition temperature, the EO coefficient of methyl nitroaniline in poly(methyl methacrylate) is shown to be due to the Kerr effect. The order parameter induced by the poling field is deduced from the electro-optical coefficient. Interpretation of the order parameter in terms of the Langevin functions alone does not agree with the experimental results.Keywords
