ABSTRACT:
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.
