Abstract :
Microdisks with various active region and different design are studied. Lasing up to 100°C is demonstrated in microrings with outer diameter 2 μm based on InAs/InGaAs quantum dots. Room temperature single-mode lasing in 9 μm microdisk lasers with InGaAs quantum dots active region is achieved.
