摘要：

We report the room-temperature operating characteristics of InGaAs/GaAs self-organised quantum dot lasers grown by molecular beam epitaxy. The emission wavelength is 1.028 mu m and J(th) = 650 A/cm(2) for a 90 mu m x 1 mm broad-area laser. Steady-state and time-resolved photoluminescence measurements confirm that lasing occurs through the e(1)-hh(2) higher-order transition, and the spontaneous recombination time for this transition is similar or equal to 200 ps.
