We report the electro-optic properties in iron-doped LiNbO3 crystals. We investigated samples with various crystal compositions and the same doping concentration. The value of the electro-optic coefficient r(c) monotonously decreases with respect to the crystal composition. To separate the influence of the intrinsic defects related to the non-stoichiometry and the effect of the introduction of iron, we compared the results with data obtained in pure LiNbO3 crystals. The effect of Fe ions on the composition of the crystal and the electro-optic properties is discussed from their site occupation in LiNbO3 lattice. (C) 2000 Elsevier Science B.V. All rights reserved.
