US6122429A - Rare earth doped barium titanate thin film .

Optical waveguides exhibiting non-linear and/or electro-optic properties comprise a rare earth doped barium titanate thin film as an optical working medium. The thin film is metalorganic chemical vapor deposited on a substrate in a reactor to incorporate rare earth atoms in-situ in the barium titanate or other ferroelectric oxide host material.

Erbium-doped barium titanate thin film waveguides for .

The factors affecting optical gain were studied for Er-doped BaTiO 3 thin film waveguides. Er-doped BaTiO 3 with dopant concentrations of 0.3 - 9 at.% was deposited by metal-organic chemical vapor deposition. The luminescence efficiency was maximized by optimizing the growth temperature and erbium concentration as well as by post-deposition annealing.
