THz and sub‐THz quantum cascade lasers

In this paper we review recent progress in obtain- ing laser action from semiconductor quantum cascade struc- tures covering the low THz region of the electromagnetic spec- trum, from 2THz (! ! 155µm) down to the sub-THz region (! > 300µm). Particularly, laser active region designs based on bound-to-continuum transition and magnetically assisted intra-well transition are presented. The wide scalability of active region designs is discussed and illustrated with experimental data. Latest results including the demonstration of laser action from quantum heterostructure at 950GHz are presented.
