Absorption and dispersion of cavity.
Calculation result of the absorption (solid blue curve) and dispersion (dashed red curve) of the cavity under the action of external driving force when δ = ω and ϕ = 0 by using Eq. (19). Setting the amplitude of external force A = 1.0 × 10−9N for panel (a) and A = 3.0 × 10−9N for panels (b–d). We use Pl = 1.49 μW in panels (a,b), Pl = 456 μW in panels (c,d). Other system parameters are taken as: m = 20 ng, ωm = 2π × 51.8 MHz, γm = 2π × 41.0 kHz, G = −2π × 12 GHz/nm, κ = 2π × 15.0 MHz and Δ = −ωm, which are chosen from the recent experiment13. we fix εp = εl/10 throughout the work since we should ensure that probe field is much weaker than control field, otherwise the perturbation method will become invalid and non-perturbative effects will occur46,49.
