摘要：

We report experimental observation of optically-pumped continuous-wave lasing from self-assembled quantum dots (QDs) embedded in high-quality factor (Q) microdisk laser structures. For large diameter (4.5 mum) microdisks containing InAs QDs, the emission spectra show simultaneous lasing on 1 to 5 well separated modes (Q = 10000 - 17000) in the wavelength range between 920 and 990 nm. For small diameter (2 mum) microdisks containing (In,Ga)As QDs, lasing occurs even when the estimated average number of QDs inside the cavity-mode volume is unity.
