Pump-probe response sensitive to atomic excitation in a hybrid optomechanical system

摘要: We study the pump-probe response in an optomechanical cavity accommodating ensemble of two-level atoms interacting with a mode, which is pumped by strong driving field and probed weak signal field. The atomic excitation examined without taking any approximations may be regimes ranging from low limit to high for given collective coupling constant between mode. This then results different absorption dispersion spectra (such as optomechanically induced transparency, Fano-resonance, normal-mode splitting) when transfer mode controlled change ineffective effective. indicates that hybrid indeed determined embedded cavity. It also interest output component inside polarization show either synchronous or asynchronous behaviors depending on how atom-field detuning chosen, i.e. equal mechanical resonator frequency its negative. Such features open up effective avenue coherently manipulating internal via external field, vice versa.
