| Abstract: | An InAs quantum-dot laser showed continuous-wave lasing up to 323 K. A high T0 of over 1000 K was measured below 130 K. The value of T0 rapidly declined at higher temperatures, and showed an oscillatory behavior above 250 K. The oscillatory changes of T 0 were accompanied by alternating change in the light output versus current curves above the threshold, suggesting possible participation of higher states in lasing |
