Abstract
Comparison of the electro-optic (EO) effect between stoichiometric and cong ruent lithium niobate (LiNbO3) crystals has been investigated using the Mac h-Zehnder interferometer at 0.633 mu m wavelength. Anisotropic changes of E O coefficients, r(33) and r(13), have been found between the stoichiometric and congruent LiNbO3 crystals. The measured r(33) value in the stoichiomet ric LiNbO3 is at least 20% larger than that of LiNbO3 with congruent compos ition, whereas the r(13) coefficient of stoichiometric LiNbO3 is the same a s that of congruent LiNbO3.
