Fig. 5: Arnold tongue for a modulation amplitudes of Pmod = ±1.9%.

a Colormap of the power spectral density (PSD). b Time traces of the transmission signal in a polar representation, where the distance to the center is the transmission value and the angle is the phase difference with respect to the maximum of the modulation signal. Each panel corresponds to a different modulation frequency, covering the spectral width of the Arnold tongue.
