AbstractElectrical injection lasers emitting in the 1.3 mu m wavelength regime based on (GaIn)As/Ga(AsSb)/(GaIn) As type-II double "W"-quantum well heterostructures grown on GaAs substrate are demonstrated. The structure is designed by applying a fully microscopic theory and fabricated using metal organic vapor phase epitaxy. Temperature-dependent electroluminescence measurements as well as broadarea edge-emitting laser studies are carried out in order to characterize the resulting devices. Laser emission based on the fundamental type-II transition is demonstrated for a 975 mu m long laser bar in the temperature range between 10 degrees C and 100 degrees C. The device exhibits a differential efficiency of 41 % and a threshold current density of 1.0 kA/cm(2) at room temperature. Temperature-dependent laser studies reveal characteristic temperatures of T-0 = (132 +/- 3) K over the whole temperature range and T-1 = (159 +/- 13) K between 10 degrees C and 70 degrees C and T-1 = (40 +/- 1) K between 80 degrees C and 100 degrees C.
