Abstract
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. Copyright © 1993 WILEY‐VCH Verlag GmbH & Co. KGaA
