Abstract :
Broad area, 100 /spl mu/m-stripe lasers, with Al-free InGaAs-InGaAsP-InGaP active regions operating at a wavelength of 0.98 /spl mu/m (0.81 /spl mu/m), provide high CW powers: 8 W (5 W) and "wallplug" efficiencies: 66 % (45 %). At 0.81 /spl mu/m, the devices are potentially twice as reliable as Al-containing active-layer devices.
