23 January 1997 Potential for fabrication of sol-gel-derived integrated optical amplifiers
Author Affiliations +
We have demonstrated the feasibility of Er/Yb co-doped strip-loaded waveguide using a glass thin film deposition process based on sol-gel chemistry. We have assessed the potentiality of using this sol-gel technology to make commercial integrated 1.55 micrometers optical amplifiers. For this purpose, we have checked the spatial uniformity of the fluorescence lifetime and losses. We have also checked the fluorescence lifetime stability over time and we have evaluated the fluorescence spectrum flatness of the material.
