Abstract
Depth profiles of titanium, iron, and niobium concentrations are inves tigated with an electron microprobe in planar optical LiNbO3:Ti wavegu ides 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.
