Fig. 4: Transition of coupled cavity and temporal two-dipole model.

a Phase spectra and the parametric polar plot of transmission for the cavity at various delays indicating the transition of coupled regime. b Comparison of experimental and calculated spectra with the temporal two-dipole model. Most of the spectral features are well reproduced in the calculation. c Reproduce the experimental transmission spectrum by applying the model to the experimental profile at steady state with tp = 55.3 ps. d Full modulation spectra at various delay times by applying the model to the temporal profile of sample at steady state. Color bar was preset within a small range for a larger color contrast.
