We investigated the electrooptic response of a set of Lithium Niobate crystals with Li concentration ranging from off-congruent to stoichiometric. Two accurate techniques based on interferometry and ellipsometry were employed to measure the electrooptic coefficients. No evidence was found of a possible enhancement of the EO response in stoichiometric Lithium Niobate with respect to the congruent one. The EO response showed a weak dispersion in the wavelength range 532-1550 nm.

Abstract
We investigated the electrooptic response of a set of Lithium Niobate crystals with Li concentration ranging from off-congruent to stoichiometric. Two accurate techniques based on interferometry and ellipsometry were employed to measure the electrooptic coefficients. No evidence was found of a possible enhancement of the EO response in stoichiometric Lithium Niobate with respect to the congruent one. The EO response showed a weak dispersion in the wavelength range 532-1550 nm.File in questo prodotto:
