High characteristic temperature of GaInNAs/GaAs narrow-ridge waveguide laser diodes grown by MOCVD

By investigating the growth-rate dependence of GaInNAs/GaAs MQW grown by MOCVD, high-performance narrow-ridge laser diodes operating at 1.3 /spl mu/m have been demonstrated with a low threshold current of 25 mA, a high characteristic temperature of 180 K, and a long lifetime of 10000 hours under 1 mW CW operation at room temperature.
