Figure 5

The absorption \(\operatorname{Re} (\varepsilon _{T})\) of the output probe field versus the normalized detuning \(\Omega /\omega _{1}\) for different values of the mechanical driving fields. The other parameters are the same as those in Fig. 2 except \(\omega _{1}=2\pi \times 10^{5}\text{ Hz}\), \(\omega _{2}=2\pi \times 0.94\times 10^{5}\text{ Hz}\), and \(\Delta =2\omega _{1}\). In Figs. 5(c)–(d), we choose \(r_{1}=r_{2}=10^{-5}\)
