Optical, compositional, and structural characterization of titanium-diffused LiNbO3 channel waveguides has been performed. The refractive index profiles have been reconstructed from near field measurements using a well-adapted mathematical approximation. Crystal lattice deformations have been measured by x-ray diffraction. Titanium concentration profiles measured by secondary ion mass spectrometry have been correlated to the refractive index profiles. The correlation between compositional, structural, and optical properties is discussed. © 2000 American Institute of Physics.
