p-doped 1.3 μm InAs/GaAs quantum-dot laser with a low threshold current density and high differential efficiency
Amodification of the thickness of the low-growth- emperature component of the GaAs spacer layers in multilayer 1.3 um InAs/GaAs quantum-dot (QD) lasers has been used to significantly improve device performance. For a p-doped seven-layer device, a reduction in the thickness of this component from 15...
