FIG. 2.

Sample transmittance as a function of the external applied voltage measured for three different polarization directions of the linearly polarized incident beam. The directions of and polarizations are depicted in Fig. 1, while the polarization denoted as was at 45° with respect to the and polarizations. The dotted lines are guide to the eye.

FIG. 3.

The intensity of transmitted light for -polarized incident beam as a function of the external voltage measured without and with the analyzer oriented orthogonal to the incident polarization (direction: ). The inset shows the dependence of the corresponding phase retardation between the - and the -polarized components of the transmitted beam on the voltage magnitude. The dotted lines are guide to the eye.

FIG. 4.

Phase retardation between the - and the -polarized components of the transmitted beam measured by translating the sample along the direction of the axis (see Fig. 1). The solid lines are fits to Eq. (4). The dotted lines are guide to the eye.
