Extremely low threshold-current-density In[SUB0.4]Ga[SUB0.6]As quantum-well (QW) lasers have been realized in the 1215-1233 nm wavelength regime. The measured room-temperature threshold current density of the InGaAs QW lasers with a cavity length of 1000 mm is only 90 A/cm[SUP2] at an emission wavelength of 1233 nm.
