Abstract
Improved MWIR MQW laser diodes with Ga0.75In0.25Sb/InAs broken-gap superlattice (BGSL) quantum wells are reported. The laser structures employ Ga0.75In0.25As0.22Sb0.78 barrier layers, and InAs/AlSb superlattice cladding layers. The Ga0.75In0.25As0.22Sb0.78 barriers yield a type-I MQW with the BGSL active region, confining both electrons and holes, as well as enhancing the optical confinement factor of the structure due to their relatively large refractive index. The thicknesses of the Ga0.75In0.25Sb/InAs superlattice constituent layers are varied to tune the emission wavelength of the devices, and a range of laser wavelengths is demonstrated.
