Abstract
InAs quantum-dot laser showed continuous-wave lasing up to 323 K. A high T- o of over 1000 K was measured below 130 K. The value of T-o rapidly decline d at higher temperatures, and showed an oscillatory behavior above 250 K. T he oscillatory changes of T-o were accompanied by alternating change in the light output versus current curves above the threshold, suggesting possibl e participation of higher state in lasing.
