Abstract

High performance 1300 nm lasers based on self-organized InAs/InGaAs quantum dots (QDs) are reported. By optimizing the QD growth parameters and decreasing the waveguide thickness, a high modal gain and a low transparency current density of 32 cm(-1) and 35 A cm(-2), respectively, were obtained from a device containing five stacked QD layers. The internal quantum efficiency is as high as 90%.
