The behavior of Single-and double-Fano resonances in the absorption (real) and dispersion (imaginary) profile of output probe field in the absence of transverse field coupling, as a function of normalized probe field detuning Δ_p/ω_m and normalized effective detuning of the system Δ/ω_m. (a,b) Contain behavior of single-Fano resonance with coupling G_a/ω_m = 0.03 and G_m/ω_m = 0. (a) Demonstrates absorption spectra of output field with different values of effective detuning Δ/ω_m = 0.84 (blue curve), Δ/ω_m = 0.87 (red curve) and Δ/ω_m = 0.90 (green curve). Similarly, (b) shows dispersion behavior of output field with effective detuning Δ/ω_m = 0.99 (blue curve), Δ/ω_m = 1.02 (red curve) and Δ/ω_m = 1.06 (green curve). (c,d) Illustrate double-Fano resonances when the atom-field and mirror-field couplings are G_a/ω_m = 0.1 and G_m/ω_m = 0.08. (c) Shows real quadrature of output field under different effective detuning strengths Δ/ω_m = 0.83 (blue curve), Δ/ω_m = 0.85 (red curve) and Δ/ω_m = 0.97 (green curve). On the other hand, (d) presents imaginary quadrature of output field with effective detuning values Δ/ω_m = 1.05 (blue curve), Δ/ω_m = 1.1 (red curve) and Δ/ω_m = 1.15 (green curve). The Fano-interactions between atomic and mechanical mirror transition levels are generating resonances with different system detuning strengths, which can be seen in the results. Remaining parameters are same as in .
