Figure 3

The absorption spectrum for In y Ga 1- y N x As 1- x , with y =4 % and x =1 % calculated using the five-level model at T =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.
