利用电磁感应透明相干光探测高激发里德堡态

Coherent optical detection of highly excited Rydberg states using electromagnetically induced transparency

A. K. Mohapatra, T. R. Jackson, C. S. Adams

摘要:

在室温铷原子蒸气池中,通过将5 p态与Rydberg态(ns或nd,n=26 ~ 124)耦合,观察到5s ~ 5 p跃迁的电磁感应透明(EIT)。我们证明,窄线宽的EIT共振(2 MHz)允许精确测量的d状态精细结构分裂,并连同灵敏度的里德堡态的电场,我们能够检测瞬态电场产生的动态细胞内的电荷。里德伯态通过EIT的相干耦合也可以用于交叉相位调制和光子纠缠。

英文摘要:

We observe electromagnetically induced transparency (EIT) on the 5s to 5p transition in a room temperature rubidium vapour cell by coupling the 5p state to a Rydberg state (ns or nd with n=26 to 124). We demonstrate that the narrow line-width of the EIT resonance (2 MHz) allows precise measurement of the d state fine structure splitting, and together with the sensitivity of the Rydberg state to electric fields, we are able to detect transient electric fields produced by the dynamics of charges within the cell. Coherent coupling of Rydberg states via EIT could also be used for cross-phase modulation and photon entanglement.
