Abstract

Diffusion techniques have provided an alternative to thin film technology for the fabrication of LiNbO(3) and LiTaO(3) light guiding layers. The effects of metal and dielectric film overlays on the propagation of TE and TM modes in diffused LiNbO(3) optical waveguides with expontential profile are investigated. Also examined are strip loaded metal-clad optical waveguides providing 2-D confinement to the light beam.
