Abstract
An InAs quantum-dot laser showed continuous-wave lasing up to 323 K. A high T/sub 0/ of over 1000 K was measured below 130 K. The value of T/sub 0/ rapidly declined at higher temperatures, and showed an oscillatory behavior above 250 K. The oscillatory changes of T/sub 0/ were accompanied by alternating change in the light output versus current curves above the threshold, suggesting possible participation of higher states in lasing.
