- We discover an unexpected behavior in a hybrid system composed of cavity strongly coupled to molecules and subjected to high intensity coherent pumping. We show that if the frequency of the pumping wave is close to polariton transitions in the hybrid system, non monotone dependence of fluorescence and scattering amplitudes on pump intensity with a narrow resonance-like response occurs. We demonstrate that this phenomenon occurs due to hybridization of lower and upper polaritons with substantially different excitation numbers caused by the pumping affecting polariton states of the system. This occurs when the Rabi interaction with coherent field is comparable to the field-matter coupling constant which in turn needs to be sufficient for the manifestation of strong coupling. This non-monotonic dependence of the fluorescence and scattering amplitudes on pump rate intensity pave the way for creation of nonlinear optical devices.
