FABRICATION OF PLANAR GRADIENT WAVEGUIDES IN PHOTO-THERMO-REFRACTIVE GLASSES
Read the full article
Gradient-index optical waveguides have been made in photo-thermo-refractive glasses by effusion and ion-exchange within different thermal and time conditions. Refractive-index profiles have been calculated. Previous radiation and thermal treatment effect on waveguide characteristics has been investigated. Keywords: photo-thermo-refractive glass, planar waveguide, ion-exchange, effusion.
