Type-II interband cascade lasers are promising in becoming efficient and compact mid-infrared (3-5 microns) light sources for many applications. Significant progress toward such a goal has recently been made in terms of lowering their threshold current densities (e.g. ~9 A/cm2 at 80 K) and raising operation temperature (e.g. 325 K in pulsed and 200 K in cw modes). Also, continuous wave operation of single-mode distributed feedback interband cascade lasers has been demonstrated. We review the recent progress of the Sb-based mid-IR interband cascade lasers and present some latest results.
