In this paper, comparison of self-assembled quantum dot lasers with and without strain compensation layers is performed. It is found that by introducing a strain compensation layers into the barriers of a multiple stacked dot active region the performance of the quantum dot layer is enhanced and the device with strain compensation show lower threshold currents, higher internal efficiencies and less absorption.
