dc.description.abstract© 2021 Kvantovaya Elektronika and IOP Publishing Limited.Semiconductor lasers based on double separate-confinement InGaAs/AlGaAs/GaAs heterostructures with a broadened waveguide are studied. The experimentally obtained samples of lasers with undoped and doped waveguide layers are compared. The differences in their current-voltage characteristics are analysed. It is found that a decrease in the series resistance and the cutoff voltage of the current-voltage characteristic makes it possible to delay the beginning of the output optical power saturation and increase the efficiency of the studied semiconductor lasers to 70% - 72%.
