We report on continuous-wave room-temperature operation at 2.014 μm of Sb-based optically-pumped vertically-external-cavity surface-emitting lasers monolithically grown on GaAs substrates by using an interfacial misfit (IMF) growth mode. The IMF is characterized by a periodic array of 90° misfit dislocation and enables the relaxed GaSb growth with a low dislocation density on lattice-mismatched GaAs after the growth of only a few monolayers of GaSb. A maximum output power of >100 mW is obtained at -5°C.
