论文摘要
使用嵌入机械谐振器中的Erbium离子的激发态证明了菌株介导的声子与电信光子之间的相互作用。由于稀土离子的寿命极长，光学共振的耗散速率低于机械谐振。因此，在光学频率区域实现了反向耗散状态。我们在实验上证明了光学机械耦合速率21.7 Hz，并在数值上揭示了相互作用会引起刺激ERBIUM离子的激发。数值分析进一步表明G_0超过ERBIUM和机械系统的耗散速率的可能性，从而导致单光子强耦合。此外，这种应变介导的相互作用涉及自旋度自由度，并且有可能扩展到反向耗散状态中高度连通的光电机力学混合系统。
Strain-mediated interaction between phonons and telecom photons is demonstrated using excited states of erbium ions embedded in a mechanical resonator. Owing to the extremely long-lived nature of rare-earth ions, the dissipation rate of the optical resonance falls below that of the mechanical one. Thus, a reversed dissipation regime is achieved in the optical frequency region. We experimentally demonstrate an opto-mechanical coupling rate 21.7 Hz, and numerically reveal that the interaction causes stimulated excitation of erbium ions. Numerical analyses further indicate the possibility of g_0 exceeding the dissipation rates of erbium and mechanical systems, thereby leading to single-photon strong coupling. This strain-mediated interaction moreover involves the spin degree of freedom, and has a potential to be extended to highly-coherent opto-electro-mechanical hybrid systems in the reversed dissipation regime.
