Figure 2

The left figure represents the reflectances, \(|{r}_{{\rm{h}}}(\omega )|\) (hot cavity) and \(|{r}_{0}(\omega )|\) (cold cavity), and the right figure represents the phase shifts \({\phi }_{{\rm{rh}}}(\omega )\) (hot cavity) and \({\phi }_{{\rm{r0}}}(\omega )\) (cold cavity) for frequency detuning \(2(\omega -{\omega }_{c})/\kappa \), according to the difference in the side leakage rates (\({\kappa }_{s}=0,{\kappa }_{s}=1.0\kappa \,{\rm{a}}{\rm{n}}{\rm{d}}\,{\kappa }_{s}=1.5\kappa \)). \(g/\kappa =2.4\) and \(\gamma /\kappa =0.1(g > (\kappa ,\gamma ))\) of the practical QD-cavity parameters are taken, and \({\omega }_{{{\rm{X}}}^{-}}={\omega }_{c}\) ^{16,19,20,21,22,24,30}.
