A 0.98 μm InGaAs/InGaAsP/GaAs strained-quantum-well laser with an exponential-shaped-flared stripe was studied. Its maximum output power with the same kink-occurrence output power was 40-60 % higher than that of ordinary straight-stripe lasers. A 150-mW lifetest showed the stable operation with an estimated lifetime of more than 200,000 hours
