Paper Abstract

LO-phonons in the active region of interband cascade lasers based on type-II multi-quantum well are investigated in detail. The dispersion relation and phonon potential for interface LO-phonon modes are calculated by the macroscopic dielectric continuum model. The expression of electron- phonon overlap with multiband k*p approximation is obtained and energy separations of hole subbands for fast LO-phonon assisted depopulations of the lower lasing state are proposed.
