Abstract :
The realization of arrays of 15 distributed feedback lasers integrated on an Er-Yb-doped phosphate glass substrate is reported. A submicronic corrugated grating has been etched on a comb of Ag/sup +/-Na/sup +/ ion exchanged waveguides with varying diffusion aperture width. Robust single frequency emission spectrum are shown, closely gauged on the 25- and 100-GHz International Telecommunications Union grids around 1.535 μm with a pump-power threshold of 14 mW and a slope efficiency of 5.7%.
