Abstract Electro-optic (EO) effect of optical superlattice LiNbO3 (OSLLN), a single crystal with periodic ferroelectric domain structure was studied theoretically and experimentally. Because the electro-optic coefficient has different signs in different domains, the refractive index ellipsoid deforms periodically in the presence of an electric field applied along the Y-axis, which results in the coupling between the extraordinary wave and ordinary wave. Under specific conditions, the… CONTINUE READING
