Modeling of Optical Waveguide Poling and Thermally Stimulated Discharge

AbsfracfA charge density and current density model of a waveguide system has been developed to explore the ef€ects of electric field electrode poling. An optical waveguide may be modeled during poling by considering the dielectric charge distribution, polarization charge distribution, and conduetion charge generated by the poling field. These charge distributions are the source of poling current densities. The model shows that boundary charge current density and polarization current density are the major source of currents measured during poling and thermally stimulated discharge These charge distributions provide insight into the poling mechanisms and are directly related to E,, and, g. Initial comparisons with expvimntpl data show excellent correlation to the model results.
