摘要：

We report interband cascade lasers (ICLs) at 3.4 mu m wavelength using bulk AlGaAsSb as the cladding layers for optical confinement, with device performance parameters at the same level as the best 5-stage ICLs using InAs/AlSb superlattice cladding layers. The threshold current density of broad area ICI, with AlGaAsSb cladding layers has been reduced from the previously reported 220 A/cm(2) at room temperature to 130 A/cm(2) at 20 degrees C. Up to 80 degrees C operation in continuous-wave mode has been obtained for a 7-mu m-wide narrow ridge waveguide ICL which has threshold current density of 177 A/cm(2) at 20 degrees C, and output power of 42 mW/facet from uncoated facet at 200 mA.
