论文摘要
从理论上讲，我们分析了强耦合混合光学力学的单光子激发和传输光谱，其中两级系统（TLS）与机械谐振器（MR）耦合，从而产生Jaynes-Cummings-cummings-type Polariton doublet。在我们的模型中，光学耦合和TLS-MR耦合都很强。在此参数区域中，二极管辅助激发和重新释放过程可以强烈影响腔体的单光激发和输出光谱。我们发现，即使在单量子水平下，每个边带周围的精细结构也可用于表征TLS-MR和有效的TLS-Photon耦合。因此，光谱结构可能使敏感探测宏观机械元素的量子性质成为可能。我们进一步提供了使用单光子传输光谱的TLS状态进行整体术重建的可能方法。
We analyze theoretically the single-photon excitation and transmission spectra of a strong-coupling hybrid optomechanics, where a two-level system (TLS) is coupled to the mechanical resonator (MR), generating the Jaynes-Cummings-type polariton doublets. In our model, both the optomichanical coupling and the TLS-MR coupling are strong. In this parameter region, the polaron-assisted excitation and reemission processes can strongly affect the single-photon excitation and output spectra of the cavity. We find that the fine structure around each sideband can be used to characterize the TLS-MR and the effective TLS-photon couplings, even at single-quantum level. Thus, the spectrum structures may make it possible to sensitively probe the quantum nature of a macroscopic mechanical element. We further provide a possible approach for tomographic reconstruction of the state of a TLS, utilizing the single-photon transmission spectra.
