Abstract
A waveguide optical amplifier include a substrate and a guiding or active layer. The substrate has a substrate surface and a substrate index of refraction. The guiding layer is of Zirconium dioxide (ZrO.sub.2) and/or Alumina (Al.sub.2 O.sub.3) and is carried on a cladding layer over the substrate surface. The guiding layer has a guiding layer index of refraction which is higher than the cladding index of refraction. The Zirconium dioxide guiding layer is doped with rare earth materials.
