Abstract We describe high-brightness, broad-area mid-IR semiconductor lasers. These devices were fabricated in our laboratory using a commercial solid-source MBE system, configured specifically for antimonide alloy deposition. The laser structures incorporated fourteen type-II quantum wells embedded in thick waveguide/absorber regions composed of $In_{0.2}Ga_{0.8}As_{y}Sb_{1-y$ . Each type-II well is comprised of a ~24 Aring thick In0.4 $}Ga_{0.6}Sb$ hole bearing layer, which is sandwiched in between two coupled InAs electron wells; as we vary the InAs thickness from 3 to 30 Aring we tune the laser from 2.5 mum to 9.5 mum
