GeSn alloys are promising materials for light emitters grown on silicon. In this work, researchers at IRIG demonstrate room temperature lasing in a GeSn hetero-structure. Their improvements include a higher tin concentration in the GeSn active layer and a better thermal dissipation provided by an adapted pedestal architecture beneath the GeSn micro-disk. This outcome is a major milestone for a fully integrated group-IV semiconductor laser on Si.
