DOIAbstract
The authors demonstrate simultaneous lasing at 2 well-sepd. wavelengths in self-assembled InAs quantum-dot lasers, via ground-state (GS) and excited-state (ES) transitions. This effect is reproducible and strongly depends on the cavity length. By a master-equation model, the authors attribute it to incomplete clamping of the ES population at the GS threshold.
