Highly strained InGaAs/GaAs quantum well vertical-cavity surface-emitting lasers

We report our results on the highly strained InGaAs/GaAs quantum well (QW) vertical-cavity surface-emitting lasers (VCSELs) in the 1140 to 1250 nm range. The epitaxial structures were grown on (100)GaAs substrates by metal-organic chemical vapor deposition (MOCVD). A maximum output power of more than 6.3 mW has been demonstrated. The spectral characteristics were also measured and analyzed.
