Abstract
The electro-optic tensor functioning is considered for crystals of 3m type symmetry at various crystallographic orientations. The most effective schemes of electro-optical phase control when light passes through the crystal are brought to light. It is shown that due to electro-optic effect the phase difference between ordinary and extraordinary beams changes when light wave passes through the crystal plate and the polarization of output radiation also changes. It is proved that, using electro-optic effect, it is possible to convert the light wave polarization for a wide range of radiation limited only by the transmission spectrum of the crystal. We take as an example the LiNbO3 crystal and calculate the range of necessary electric fields to provide its functioning in the half and quarter wave plates mode over the wavelength range of 0.4-4.5 μm.
