Optically pumped terahertz lasers based on interband transitions in type-II antimonide heterostructures are proposed and modeled in detail. At cryogenic temperatures, the activated nature of the Auger and phonon-assisted mechanisms should provide substantially longer nonradiative lifetimes and higher gains than are attainable with intersubband devices. For emission at λ=27 μm, pulsed operation is projected up to 60 K, and 〉25 mW of cw output power is calculated for T=30 K. At T=4 K, lasing is expected out to wavelengths as long as 100 μm. © 1999 American Institute of Physics.
