Abstract

Planar optical waveguides were fabricated using an electric field-assisted potassium ion-exchange in soda-lime glass substrates. Mode index measurements were made for the purpose of establishing formulas for the effective diffusion constant guide depth and refractive index change given the electric field the diffusion temperature and the time. The index profile could be accurately modeled by a modified Fermi function with significant improvement over the step-index model. The potassium ion concentration profile was determined using a scanning electron microscope (SEM) technique which is then correlated to the numerical simulation of the ion-exchange fabrication process.
