Characterization of the poling process in zinc diffused lithium tantalate optical waveguides Academic Article uri icon


  • A model for the poling process of Zn diffused LiTaO3 optical waveguides that is based on the thermodynamic theory of ferroelectrics is presented. The effect of oppositely oriented domain regions are related to the linear electro-optic coefficient by the approximation that the polarization inside the crystal is proportional to the external electric field applied during poling. The model predictions agree well with experimental optical phase shift data of electro-optic waveguide modulators produced by diffusions above the Curie temperature then repoled under different electric field values. © 1993, Taylor & Francis Group, LLC.
