(a) Real part nR and (b) imaginary part nI of the refractive index as functions of position x and probe detuning Δp. The parameters are δΩc = 0.3Γ and δΩd = 0.1Γ. (c) Real part nR and (d) imaginary part nI of the refractive index as functions of position x and modulation intensity δΩd. The parameters are Δp = 2.525 meV and δΩc = 0.3Γ. (e) Real part nR and (f) imaginary part nI of the refractive index as functions of position x and modulation intensity δΩc. The parameters are Δp = 2.525 meV and δΩd = 0.1Γ. The other parameters are the same as in Fig. 11.
