- Abstract
The main characteristics of edge-emitting lasers with active regions based on nanoheterostructures of a new type—quantum well-dots (QWDs) operating at various wavelengths—are compared. The QWD structures operating at 980- and 1080-nm wavelengths demonstrated minimum values of threshold current density (160 and 125 A/cm2), high internal quantum efficiency (74 and 85%), and low internal losses (1.1 and 0.9 cm–1), respectively.
