Abstract
The electronic structure and optical absorption spectra of coupled qua ntum wires InAsxP1-x/InP are studied within the framework of the effec tive-mass envelope-function theory. The valence subband dispersion, th e energy levels at the Gamma-point, the squared optical transition mat rix elements, and the absorption spectra near the band edge are calcul ated. The coupling effects among heavy hole, light hole, and spin-spli t-off bands are presented.
