Summary form only given. We report calculations of band structures, optical gain, and threshold current density in mid-IR type-II interband cascade lasers. Implications of the calculated results will be discussed in connection with device performance. Our calculations are based on Kane's eight-band k.p model with envelope wavefunction approximation and strain effects included. The band structures for InAs-GaInSb-AlSb QW active region in a type-II interband cascade laser at 80 K and 300 K are computed with a constant electric field F.
