腔光力学作为纳米光子学与量子力学的交叉学科，为研究微腔内光子与机械模式的声子之间的光力耦合作用提供了一个独特的平台。其在量子物理领域存在广泛的潜在应用，已成为当今物理研究的前沿课题。本文提出了一种利用两能级原子系综增强和边带产生的理论方案。通过引入两能级原子介质，研究了原子系综的失谐频率对于和边带产生效率的影响。结果表明不论在原子红失谐还是蓝失谐下都可以使和边带的生成效率得到显著增强，并且对于红失谐状态下的依赖性更大，其增强的效果更加明显。此外，我们还考虑了泵浦功率的影响，通过选择适当的泵浦功率可以有效的增强输出和边带信号的强度。另外，讨论了腔-原子耦合强度与原子衰减率对于和边带信号传输特性的影响，通过测量和边带频率谱的峰值，进而检测出腔与原子间的耦合强度。这为腔-原子耦合强度的精密测量提供了一种简单便捷的方法，同时也为和边带信号传输的调控提供有益的借鉴。Cavity optomechanics, as a cross-discipline between nanophotonics and quantum mechanics, provides a unique platform for the research of optomechanical coupling between photons in microcavities and phonons from mechanical modes. It has a wide range of potential applications in the field of quantum physics and has become a hot topic nowadays. A theoretical scheme to enhance the sum sideband generation (SSG) via two-level atom ensemble is proposed. The effect of the atomic ensemble’s detuning frequency on the efficiency of the SSG is considered by introducing a two-level atom medium. The results indicate that the efficiency of the sum sideband generation can be significantly enhanced under either red or blue detuning of the atoms, with a greater dependence and more pronounced enhancement under red detuning. In addition, we also consider the effect of pump power, which can effectively enhance the intensity of the output signal by selecting the appropriate pump power. More interestingly, the sensitivity of SSG to atomic detuning also indicates that precise control of the atomic detuning frequency can enable fine-tuning of the SSG process. Furthermore, the cavity-atom coupling strength and atom decay rate are discussed for the transmission characteristics of the sum sideband signals. It was found that the efficiency of SSG can be effectively adjusted by the cavity-atom coupling strength and atom decay rate. The results show that the efficiency of SSG can be significantly improved by optimizing system parameters. The enhanced SSG method may have potential application prospects in realizing the measurement of high-precision weak forces and on-chip manipulation of light propagation.
