Caption

a, Schematic diagram of the PT-symmetric coupled microresonators. b, Energy ladder of the PT-symmetric coupled microresonators. (c), Experimental evolution of the eigenvalues of the passive PT symmetry system. (d), Transmission spectra of the systems. The blue solid lines represent the measured transmission spectra, while the red dashed lines represent their curve fittings for devices operating at different coupling conditions. Panel (i) to (v) correspond to the blue data points shown in Fig. 1a from left to right.
