The absorption spectrum for InyGa1-yNxAs1-x, withy=4% andx=1% calculated using the five-level model atT=10 K. The contribution of the transitions between three valence bands and three conduction sub-bands are shown. The solid arrows designate the transitions from HH and LH bands to lower (l), middle (m) and upper (u) conduction sub-bands. The dashed arrows indicate the transitions from spin-orbit split-off band to conduction sub-bands.
