The transmitted intensity of the probe field U_t versus the incident intensity U_in for different coupling fields. The solid line corresponds to Ω_c = 0.2, dashed line corresponds to Ω_c = 2, and dotted line corresponds to Ω_c = 5. The other selected parameters used are ɛ_b = 4, λ₀ = 1.55 μm, Δ_p = 0.5, Δ_c = 0, γ_i = 1, γ_a = γ_b = 0, and β = 0.
