Multiple layers (up to 10) of InAs/InGaAs/GaAs quantum dots considerably enhance the optical gain of quantum dot lasers emitting around 1.3 muM. A differential efficiency as high as 88% has been achieved in these lasers. An emission wavelength of 1.28 mum, threshold current density of 147 A/CM2, differential efficiency of 80%, and characteristic temperature of 150 K have been realised simultaneously in one device.
