(a) The power transmission coefficient \(|t_{p}|^{2}\) as functions of the normalized detuning \(\Omega /\omega _{1}\) for different values of the amplitude ratio \(r_{1}\) with \(\Phi _{1}=1.5\pi \). (b) The transmission coefficient \(|t_{p}|^{2}\) at \(\Omega =2.00362\omega _{1}\) versus the amplitude ratio \(r_{1}\) with \(\Phi _{1}=1.5\pi ,0\), and 0.5π, respectively. The other parameters are the same as those in Fig. 6 except \(r_{2}=10^{-5}\) and \(\Phi _{2}=0.5\pi \)
