OPTICAL LOSS IN INAS-BASED LONG-WAVELENGTH LASERS

A microscopic quantum-mechanical analysis of the intervalence band abs orption of radiation (IVA) with hole transition into the spin-orbit sp lit-off band has been made. It was found that IVA can heavily influenc e the threshold characteristics and quantum efficiency of heterolasers based on InAs. A detailed study of the threshold characteristics as f unctions of temperature and heterostructure parameters has been analyz ed taking into account IVA. (c) 1998 American Institute of Physics.
