论文摘要
嵌入量子井的半导体微孔子可以立即托管紧密限制和相互相互作用的激子，光学和机械模式。从理论上讲，我们研究了系统以强烈的激子 - 光子耦合方式运行的情况，而光学和激子共振是通过与机械模式的相互作用进行参数调节的。由于在半导体中播放时在播放时具有大的激子 - 子耦合，因此我们预测，相对于仅纯净的光学机械耦合，通过两个数量级来增强Polariton-Phonon相互作用：一个近乎单位的单位 - 单位 - 单位 - 核心量子量量，目前的半导体共振器平台可以触及。我们进一步分析了极化非线性如何影响动态反作用，从而改变了冷却或放大机械运动的能力。
Semiconductor microresonators embedding quantum wells can host tightly confined and mutually interacting excitonic, optical and mechanical modes at once. We theoretically investigate the case where the system operates in the strong exciton-photon coupling regime, while the optical and excitonic resonances are parametrically modulated by the interaction with a mechanical mode. Owing to the large exciton-phonon coupling at play in semiconductors, we predict an enhancement of polariton-phonon interactions by two orders of magnitude with respect to mere optomechanical coupling: a near-unity single-polariton quantum cooperativity is within reach for current semiconductor resonator platforms. We further analyze how polariton nonlinearities affect dynamical back-action, modifying the capability to cool or amplify the mechanical motion.
