摘要
Low threshold lasers based on GaInSbAs/GaSb type-II QW structures operating between 2 and 2.4 mu m at room temperature have been fabricated. The RT threshold current density as low as 305 A/cm(2) was obtained for a 900-mu m-long laser emitting at 2.36 mu m. High efficiency of indirect radiative recombination is explained by accumulation of holes in potential wells situated in barrier layers near the QW interfaces.
