From: Tunable optical nonreciprocity in double-cavity optomechanical system with nonreciprocal coupling
The isolation ratio \(\textrm{I}\) of the probe field nonreciprocal transmission is plotted as a function of the coupling strengths \(\lambda _{1}\) and \(\lambda _{2}\). We use \(\mathrm {P_c}=0\) \(\mu\)W, \(\kappa _2=0.5\kappa _1\), and the other parameters are the same as in Fig. 2.
