论文摘要
电子共振可以显着增强腔磁力机械中的光子光子耦合，但由于吸收损失并通过不均匀的拓宽而进行逐渐避免，因此通常可以避免。我们通过实验表明，半导体微腔中的激子 - 果龙可以使GHz光学力学具有单粒子谐振耦合，在MHz范围的10s中达到了创纪录的值。此外，这种谐振增强受到了Rabi Gap的不均匀扩大的保护。单极非线性和光力强耦合方案在此平台中可以访问。
Electronic resonances can significantly enhance the photon-phonon coupling in cavity optomechanics, but are normally avoided due to absorption losses and dephasing by inhomogeneous broadening. We experimentally demonstrate that exciton-polaritons in semiconductor microcavities enable GHz optomechanics with single-particle resonant couplings reaching record values in the 10s of MHz range. Moreover, this resonant enhancement is protected from inhomogeneous broadening by the Rabi gap. Single-polariton non-linearities and the optomechanical strong-coupling regime become accessible in this platform.
