Abstract
SiO2—GeO2 planar waveguides, doped with Eu3+ ions, have been prepared using the dip-coating technique. Optical characterization of the waveguides has been performed by m-line spectroscopy. The structural modification occurring during the densification process has been followed by waveguide Raman and luminescence spectroscopies. A strong rearrangement in the glass occurs after annealing at 900°C and the final structure appears more ordered.Keywords
