Figure 6

The appearance of OB and OM at two probe frequency regions: Δp = 0 (a) and Δp = 2γ (b). Other parameters are Δc = 0, Ωs = 5γ, Δs = 5γ, B = 2γc and C = 100γ, while the coupling laser intensity is varied as indicated in the figures. Variations of absorption and dispersion versus the coupling laser intensity at two probe frequency regions: Δp = 0 (c) and Δp = 2γ (d) with other parameters similar to those in figures (a,b).
