The absorption spectrum for InyGa1-yNxAs1-x withy=4% andx=1%. The red dashed line and blue squares represent the absorption spectrum calculated using the five-level BAC model and the SCGF including the LCINS distribution of localised states (obtained for GaN 0.012As0.988), respectively. The black dots and line show the measured and calculated spectrum by Skierbiszewski  at temperature 10 K.
