(color online) Amplitude |T(x)| (red dashed line) and phase ϕ(x) (blue solid line) of the transmission function T(x) plotted over two space periods for different two-photon detunings: (a1) δ₁ = 0.5γ^′, δ₂ = −2.5γ^′; (b1) δ₁ = 1.5γ^′, δ₂ = −1.5γ^′; (c1) δ₁ = 2.5γ^′, δ₂ = −0.5γ^′. ((a2), (b2), and (c2)): Plots of diffraction pattern I(θ) versus sin θ corresponding to the (a1), (b1), and (c1) cases. Parameters are Ω_s = 4.5γ, L = 3 mm, M = 6, and Λ = 4λ_p. Other parameters are the same as those in Fig. 2.
