Abstract
Extremely low threshold-current-density In 0.4 Ga 0.6 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 μm is only 90 A/cm 2 at an emission wavelength of 1233 nm.Keywords
