Abstract :
For the fabrication of optical waveguides, a silver film was vacuum-evaporated onto a glass substrate and then annealed at 300-400°C while applying an external electric field (0-70 V/mm) perpendicular to the substrate surface. The enhancement of the index of refraction (0-0.080) was larger for a stronger electric field. Index profiles of waveguides were determined with a scanning electron microscope (SEM) and the prism-coupling technique was used to find the number of guided modes. The eigenmode equation was numerically solved to find the relationship among the diffusion profile, index change, and number of guided mode. The index change was confirmed with Rutherford backscattering spectrometry (RBS) analyses
