(a) Comparison of transmission rates corresponding respectively to absorption process (red), OMIT (blue), inverted-OMIT (green) and inverted-OMIT in ref. 26. Here we set g = 7.4 × 10−4γ, γm = 0.38γ and Ωd = 5000γ. The absorption, OMIT and inverted-OMIT respectively correspond to J = 0, 0.2501(γ + κ) and (γ + κ); κ = 0, 10−4γ and 0.05γ. The inset in (a) is the comparison of transmission rates corresponding to OMIT (blue, κ = 10−4γ) and optomechanically induced amplification (red, κ = 10−2γ). (b) Comparison of transmission rates corresponding to γ = 1/23 (blue), γ = 2/23 (green) and γ = 4/23 (black) with γm = 0.38γ. Here the other parameters are the same with the Fig. 2.
