论文摘要
极化子使激子和光子的谐振耦合能够与应用相关的超高频（SHF，3-30 GHz）域中的振动。我们引入了一个新型平台，以基于激子 - 孔子和电动驱动的SHF纵向声音子的耦合，用于相干的光学力学，并限制在平面bragg microcavity的间隔区域内的纵向声音。微腔平台的固有特性是通过样品边界的反射对声子进行回馈，这使频率X质量因子产品超过10^14 Hz以及光学过渡能的巨大调制振幅（最高8 MEV）。我们表明，调制由激子极化子组件的声子诱导的能量移位所支配，因此导致弱和强光 - 偶联耦合方案之间的振荡过渡。这些结果为基于极化的相干光学力学开辟了道路，在相干控制的非绝热，侧带分辨状态下。
Polaritons enable the resonant coupling of excitons and photons to vibrations in the application-relevant super high frequency (SHF, 3-30 GHz) domain. We introduce a novel platform for coherent optomechanics based on the coupling of exciton-polaritons and electrically driven SHF longitudinal acoustic phonons confined within the spacer region of a planar Bragg microcavity. An intrinsic property of the microcavity platform is the back-feeding of phonons via reflections at the sample boundaries, which enables frequency x quality factors products exceeding 10^14 Hz as well as huge modulation amplitudes of the optical transition energies (up to 8 meV). We show that the modulation is dominated by the phonon-induced energy shifts of the excitonic polariton component, thus leading to an oscillatory transition between the regimes of weak and strong light-matter coupling. These results open the way for polariton-based coherent optomechanics in the non-adiabatic, side-band-resolved regime of coherent control.
