Abstract

Mach-Zehnder interferometry (MZI) was applied to a LQ-2200 polyimide thin film with a coplanar electrode to determine the Pockels coefficients. A glass plate was positioned on a computer-controlled rotational stage providing optical bias for reference arm. The incident light with a polarization angle θ was obtained from the Fresnel relation and the interference pattern of the light from MZI was given in an equation. The maximum and the minimum MZI interference intensities are related to the light amplitudes at the two arms of the MZI. The modulation intensity is plotted as a function of the polarization angle. The solid curve is fitted to the data points with the tensor ratio predicted by the thermodynamic model as the fitting parameter.
