Abstract
We have measured electro-optic coefficients at 94 GHz for several orientations in LiNbO3 and LiTaO3. These coefficients are considerably enhanced over their values in the visible, due to contributions from lattice vibrations. A scaling law is developed which allows the calculation of these coefficients in terms of the linear susceptibility. The phase shifting performance of a number of promising materials is discussed.
