(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 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 = 2.592 meV. The other parameters are the same as in Fig. 7.
