This paper summarizes recent developments in the search for materials and designs that can lead to lasing without global population inversion in the far infrared based on intersubband devices. The recent proposal of using the strong k-dependence of the transverse electric dipole moment to filter local inversion of nonequilibrium holes in the valence subbands of III-V quantum wells is discussed
