摘要：

The wavelength of InAs quantum dots in an In-0.15 Ga0.85As quantum-well (DWELL) lasers grown on a GaAs substrate has been extended to 1.3-mu m. The quantum dot lasing wavelength is sensitive to growth conditions and sample thermal history resulting in blue shifts as much as 73 mn. The room temperature threshold current density is 42.6 A cm(-2) for 7.8-mm cavity length cleaved facet lasers under pulsed operation.
