Abstract
Lasing via the ground state of an exciton in vertically coupled quantu m dots all the way to 300 K is demonstrated for the first time. At 80 K, the threshold current density was J(th)similar to 40 A/cm(2) The te mperature dependence of the threshold current density in the range 80- 180 K is described by a characteristic temperature of T-o=430 K.
