Paper Abstract

The relaxational response of a photorefractive polymer subjected to different poling voltages slightly above the glass transition temperature is measured using ellipsometry. We discuss our results using a new curve-fit function, which provides a good description of the experimental data. Using this new function we examine how the poling voltage influence the poling behavior of the chromophores. Furthermore, it is shown that the characteristic time for turn-off behavior is strongly influenced by the time span elapsed since turn-on.
