Paper Abstract

The electronic structures of (InAs)m/(GaSb)n short- period superlattices are investigated by the empirical pseudo potential method and multiband kp envelope function approximation with the same underlying bulk band structures. The calculated result are compared to each other and with experiment. Generally, the results of the empirical pseudo potential method are in better agreement with the experimental measurement. The superlattice active region of an optically-pumped type-II laser are investigated by the empirical pseudo potential method. The calculated result predict that its lasing wavelength is about 3.5 micrometers at 80K and internal losses due to intervalence absorption have been suppressed.
