Zusammenfassung: 
Depth profiles of titanium, iron, and niobium concentrations are investigated with an electron microprobe in planar optical LiNbO3:Ti waveguides additionally doped with iron. The profiles are well described by Gaussian functions allowing the determination of diffusion constants. The extraordinary refractive index of the waveguides can be described by a linear superposition of iron and titanium profiles.
