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.

通过混合光机系统中的量子位-机械非线性相互作用进行可切换和增强的吸收

我们分析研究混合光机系统(HOMS)输出场的特征,该系统包括一个典型的光机组件和一个超导量子位,该量子位通过非线性相互作用与膜耦合(也由驱动场激励)。非线性相互作用导致生成附加的OMIT窗口。我们报告了一种通过适当调整机械驱动场的强度和相位来调节光学响应的​​有效方案。有趣的是,机械驱动场的作用是同时根据机械驱动场的相对相位和强度来增强红色(蓝色)失谐区域或蓝色(红色)失谐区域的吸收(放大)。此外,干扰效应表明,在共振点的任一侧,信号场的传输都可以大大增强或停止存在。此外,相对相位可以显着调整信号场的传输频谱。我们发现,边带区域周围的相位效应比不透明点要明显得多。对在这种HOMS中操纵透射光谱的研究证明,所提出的方案可以用于光开关/晶体管中。
