Paper Abstract

Two layers of buried optical waveguides are manufactured in silicate glass substrate. Using ion-exchange process, this procedure is composed of two successive cycles of buried waveguide fabrication. Characterizations of these waveguides show that the two layers have similar dimensions for both waveguide core and for mode field, and thus similar optical properties. Loss analysis indicates that coupling loss of top and bottom layer waveguide with single-mode-fiber being 0.80  dB/facet and 0.75  dB/facet, respectively.
