This article reports the optimum design, device fabrication and characterization of a very low threshold current ridge waveguide ~ 0.85μm GaAs / AsGaAsGRIN-SCHSQW laser diode. Very low threshold current of 2.2-4 mA and differential quantum efficiency of ~ 0.6 mW / mA were obtained. 70 ℃, 3mW constant power life test, suggesting that the average working life of the device is greater than 40,000 hours.
