abstract = "Molecular beam epitaxy-grown 0.98-μm vertical-cavity surface-emitting lasers (VCSELs) with a three-stack submonolayer (SML) InGaAs quantum-dot (QD) active region and fully doped AlxGa1-x As-GaAs DBRs was studied. Large-aperture VCSELs demonstrated internal optical losses less than 0.1\% per one pass. Single-mode operation throughout the whole current range was observed for SML QD VCSELs with the tapered oxide apertures diameter less than 2 μm. Devices with 3-μm tapered-aperture showed high single-mode output power of 4 mW and external quantum efficiency of 68\% at room temperature.",
