Second-order sideband effects mediated by microwave in hybrid electro-optomechanical systems

• Second-order sideband effects in a hybrid electro-optomechanical system are researched.
• The influences of the microwave signal on the second-order sideband generation are detailedly discussed.
• The second-order sideband generation can be modified just by tuning the power or the detuning of the microwave signal.
• Strong second-order sideband effect can be induced in such a three-mode optomechanical system.

We theoretically investigate the second-order sideband effects in a hybrid electro-optomechanical system, and mainly focus on the influence of the microwave signal on the second-order sideband generation. The numerical results show that just by tuning the power and the detuning of the microwave signal, the second-order sideband can be significantly modified. More importantly, while driving this hybrid system by a blue detuned microwave with suitable power, strong second-order sideband effect can be induced. These results can find potential applications in optical frequency converters in the quantum information processing.
