In this paper we investigate the possibility of producing local population inversion that can lead to lasing without inversion by engineering the conduction band effective masses in dilute nitride structures so that the upper lasing subband has an effective mass considerably smaller than the lower lasing subband that could not be obtained in usual IIIV materials. This analysis is the first step towards possible far infrared dilute nitride based quantum cascade lasers that could benefit from the gain without inversion effect to operate at higher temperatures.
