Abstract
The Electro-Optical coefficients in test samples of two different second-order nonlinear optical polymers (with Tg's of 140 degree(s)C and 175 degree(s)C) have been measured between crossed polarizers (r33-r13) and Fabry-Perot interferometrically (r13), both during poling and after poling. In the polymer with Tg 140 degree(s)C, the dependence of the coefficients on the strength of the poling field, and the ratio r33/r13 have been investigated and compared with theory. A quasi-instantaneous loss of field induced Electro- Optical activity is observed when the poling field is switched off after poling. The influence of annealing on the relaxation behavior is discussed. Results of relaxation experiments in the two polymers at different temperatures are presented.
