In this work, the highly strained In0.39 Ga0. 61As-GaAs lasers grown by metal-organic vapor phase epitaxy were studied. The InGaAs lasers could emit at 1.22 μm under continuous-wave conditions, whereas the threshold current density (Jth) and transparency current density (Jtr) were 140 and 37.2 A/cm2, respectively. To the best of our knowledge, the Jtr was the lowest among the reported InGaAs lasers longer than 1.2 μm. The characteristic temperature (T0) was 146.2 K indicating the good temperature stability. These excellent laser characteristics could be attributed to the optimized growth conditions.
