High-power multiple-quantum-well distributed feedback laser arrays and Fabry-Perot laser arrays at 1.5/spl mu/m wavelength

We report on coherent high-power 12-element laser arrays of both the DFB and FP types. Pulsed emission up to 450 mW/facet and CW output to 85 mW are demonstrated with a single-wavelength spectrum for DFB arrays and multi mode output from FP arrays.
