摘要:
We have successfully operated GaInNAs laser diodes with a pulsed current at room temperature. The lowest threshold current density was about 0.8 kA/cm(2), and the lasing wavelength was about 1.2 mu m. Characteristic parameters such as internal quantum efficiency and the gain constant were measured, and excellent high-temperature performance was observed. The characteristic temperature was 127K in the temperature range from 25 to 85 degrees C.
