Paper Abstract

The electro-optic effect in an electric-field-aligned side-chain polymer is investigated. The polymer contains dipolar hyperpolarizable molecules as pendant groups. The hyperpolarizable group is 4-oxy-4'-nitrostilbene. The dielectric strength of the polymer material has been measured and is over 200 MV/m. Measurements on the electro-optic coefficients are reported. Two experimental methods are used. From a crossed-polarizers set-up r33-r13=0.58 pm/V is obtained. From an interferometric set-up r13=0.27 pm/V is obtained. Combining the results of both methods yields r33=0.85 pm/V and r33/r13=3.1. The results are in agreement with theoretical predictions based on the isotropic model for electric-field-induced alignment.
