Abstract

Comparison of the electro-optic (EO) effect between stoichiometric and congruent lithium niobate (LiNbO₃) crystals has been investigated using the Mach-Zehnder interferometer at 0.633μm wavelength. Anisotropic changes of EO coefficients, r₃₃ and r₁₃, have been found between the stoichiometric and congruent LiNbO₃ crystals. The measured r₃₃ value in the stoichiometric LiNbO₃ is at least 20% larger than that of LiNbO₃ with congruent composition, whereas the r₁₃ coefficient of stoichiometric LiNbO₃ is the same as that of congruent LiNbO₃.
