Switchable and Enhanced Absorption via Qubit-Mechanical Nonlinear Interaction in a Hybrid Optomechanical System

We analytically investigate the features of the output field of a hybrid optomechanical system (HOMS) comprising a typical optomechanical component and a superconducting qubit which is coupled with the membrane (which is also excited by driving field) through nonlinear interaction. The nonlinear interaction leads to generate an additional OMIT window. We report an effective scheme to modulate the optical response by suitable adjustment of the intensity and the phase of mechanical driving field. Interestingly, the effect of mechanical driving field is to enhance the absorption(amplification) either in the red(blue)-detuned regions or in the blue(red)-detuned regions simultaneously depending upon the relative phase and intensity of the mechanical driving field. Furthermore, the interference effects show that the transmission of the signal field can be greatly enhanced or ceased to exist in either side of the resonance point. In addition, relative phase can significantly tune the signal field's transmission spectrum. We find that the phase effect around the sideband regions is much prominent than at the opacity point. The study of the manipulating the transmission spectra in such HOMS proves that the proposed scheme can be utilized in optical switches/transistors.

Automated summary

The output field features of a hybrid optomechanical system (HOMS) are analytically investigated. The nonlinear interaction and mechanical driving field modulation can generate an additional OMIT window and enhance absorption or amplification in specific regions depending on the relative phase and intensity. Manipulating transmission spectra in such HOMS may have applications in optical switches/transistors.
