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