Paper Abstract

Quadratic electrooptic modulation of thin dye-doped polymer films is used to evaluate the electronic third-order susceptibility, χ(3) . To determine this susceptibility, the other contributing mechanisms, including orientational effects, electrostriction, electrode attraction, trapped charge movement, and heating, must be considered. The two dominant non-electronic effects are the orientational effect and the electric field-induced electrooptic effect. The degree of molecular motion of the dye molecules in the polymer matrix is measured with electric field-induced second-harmonic generation below the glass transition temperature of the composite. The microscopic orientational elastic constants, as determined from these second-harmonic measurements, are used to predict the orientational contributions. The molecular electronic third-order susceptibility of a poly(methyl methacrylate)/azo dye system, determined with the electrooptic measurement, is consistent with values derived from third-harmonic generation measurements.
