title = "Characterisation of InGaAs/GaAs quantum dot lasers grown by metal-organic vapour phase epitaxy",
abstract = "A major problem facing quantum dot lasers is gain saturation. This is caused by low gain volume and also a low wavefunction overlap within the quantum dots. One method to increase the gain volume is to increase the number of layers of quantum dots. This paper compares the characteristics of lasers with three and five layers of quantum dots. It is shown that five layer devices can be made with improved efficiency and wavelength characteristics without a significant increase in the losses.",
