Abstract

Deterioration of the gain coefficient as a result of UV processing of hydrogen-loaded ${\mathrm{Er}}^{3+}$- and ${\mathrm{Er}}^{3+}/{\mathrm{Yb}}^{3+}$-doped silicate optical waveguides can be reduced by initial hypersensitization of the waveguide prior to bulk irradiation. This allows improved performance in active-grating devices such as distributed-feedback fiber amplifiers and lasers.
