Description
We report the observation of the frequency nonlinearity during amplitude stabilization of the gain-embedded resonator which was previously interpreted as a van der Pol oscillator. Our investigation reveals that this specific nonlinear oscillationn is more accurately described by the van der Pol-Duffing oscillator model. We initially observed this phenomenon in a gain-embedded circuit oscillator and noted bistable behaviour upon coupling with a damped resonance. Then, in a gain-embedded cavity, we experimentally verified this nonlinear phenomenon. The bistable behavior of the cavity-magnonic polariton is well-fitted by this van der Pol-Duffing model.
