Abstract :
Summary form only given. We present results from 100-/spl mu/m stripe DFB lasers, which operate at 1.1 W cw with a linewidth of 0.9 W and at 1 W quasi-cw (5 /spl mu/s, 2 kHz) with a linewidth of 1.2 A. These SCH lasers use a broad-waveguide structure consisting of an InGaAs DQW active region within an InGaP optical confinement region and InGaAlP cladding layers.
