声子-激子和声子-光子耦合干涉驱动的光机械放大

Optomechanical amplification driven by interference of phonon-exciton and phonon-photon couplings

Egor S. Vyatkin, Alexander N. Poddubny

摘要:

本文从理论上研究了零维微腔中激子极化激元与振动相互作用的光机阻尼和放大谱。我们证明,光谱强烈地依赖于激子-声子和光子-声子耦合常数的比例。这些耦合之间的干扰使得能够实现这样的情况,即当光机械增益仅存在于较低的极化激元共振或仅存在于较高的极化激元共振时。我们的研究结果提供了在各种多模系统中的光机械相互作用的见解,其中几个谐振振荡器,如光子,等离子体激元,或激子耦合到相同的振动模式。

英文摘要:

We study theoretically optomechanical damping and amplification spectra for vibrations interacting with excitonic polaritons in a zero-dimensional microcavity. We demonstrate, that the spectra strongly depend on the ratio of the exciton-phonon and the photon-phonon coupling constants. The interference between these couplings enables a situation when optomechanical gain exists either only for a lower polaritonic resonance or only for an upper polaritonic resonance. Our results provide insight in the optomechanical interactions in various multi-mode systems, where several resonant oscillators, such as photons, plasmons, or excitons are coupled to the same vibration mode.
