16 December 1993 Dielectric characterization of nonlinear optical polymers
Author Affiliations +
Two nonlinear optical polymers, containing the active molecules in the main-chain and in the side-chain, have been characterized by dielectric spectroscopy in the frequency range from 0.05 Hz to 10 kHz. It is shown that dielectric spectroscopy is a powerful technique to monitor the mobility (relaxation) of active molecules. From the results a estimation about the poling temperature and -time can be made. In addition, the influence of absorbed water on the relaxation is established as well as the effect of UV-light exposure on the chromophores.
