Abstract :
A dense array of InGaAs quantum dots formed by MOCVD on a misoriented GaAs substrate has been used as an active medium of microdisk resonators of various types: a cylindrical disk, an undercut disk, and a suspended disk. Single-mode room temperature lasing in a 9-μm microdisk laser is demonstrated with a dominant line around 1.13 μm. Impact of the resonator design on the lasing threshold and its temperature behavior is discussed.
