Abstract
Poled polymer thin films are studied by SHG, THG, and ATR experiments. The ATR method is used for determining the linear and quadratic electro-optic (chi) (2) (-(omega) ; 0, (omega) ) and (chi) (3) (-(omega) ; 0, 0, (omega) ) coefficients. The part due to the piezoelectricity and electrostriction is characterized and it is shown that in some cases the mechanical strains are more important than the direct electro-optic effect. From SHG experiments, the degree of orientation linked to the (chi) (2) (-2 (omega) ; (omega) , (omega) ) susceptibility can be evaluated. The various results are presented in this paper.
