From: Ringing phenomenon in chaotic microcavity for high-speed ultra-sensitive sensing

Green and orange curves show the mapped RP spectra of the chaotic and the symmetric WGM microcavities, respectively, without adsorbates.
Red and blue curves show the simulated RP spectra with a molecule adsorbed on the microcavities when the frequency detune equals to −5 MHz, as indicated by the black arrow.
