Real part nR and imaginary part nI of the refractive index as a function of position x for unchanged absolute value and different signs of Δp, δΩc and δΩd, respectively, (a) Δp = 2.525 meV, δΩc = 0.3Γ and δΩd = 0.1Γ, (b) Δp = 2.525 meV, δΩc = 0.3Γ and δΩd = −0.1Γ, (c) Δp = 2.525 meV, δΩc = −0.3Γ and δΩd = 0.1Γ, (d) Δp = 2.525 meV, δΩc = −0.3Γ and δΩd = −0.1Γ, (e) Δp = −2.525 meV, δΩc = 0.3Γ and δΩd = 0.1Γ, (f) Δp = −2.525 meV, δΩc = 0.3Γ and δΩd = −0.1Γ, (g) Δp = −2.525 meV, δΩc = −0.3Γ and δΩd = 0.1Γ, (h) Δp = −2.525 meV, δΩc = −0.3Γ and δΩd = −0.1Γ. The parameters are Ωc0 = 3Γ and Ωd0 = Γ. The other parameters are the same as in Fig. 6.
