We discuss an improved mid-wave infrared diode laser structure based on InAs-Ga1−xInxSb- InAs-Ga1−xAlxSb Type-II multiple quantum wells. The proposed design combines strong optical coupling, 2D dispersion for both electrons and holes, suppression of the Auger recombination rate, and excellent electrical and optical confinement.
