摘要:

对腔-原子系综系统进行了实验研究,实现了探测激光和控制激光均与法布里-珀罗腔共振的双共振腔增强电磁感应透明。我们展示了精确的频率操纵的混合光学原子共振,通过温度或腔长调谐。在这样的系统中,控制功率可以大大提高由于腔,和全光开关是实现了与以前的研究相比,控制激光功率低得多。本文提出了一个新的理论模型来描述自旋波与光学模之间的有效三波混频过程。有趣的非厄米物理的理论预测和实验证明。这种无需特殊腔体的双共振腔-原子系综系统可用于未来的应用,如光信号存储和微波-光频率转换。

英文摘要:

We present an experimental study on the cavity-atom ensemble system, and realize the doubly-resonant cavity enhanced electromagnetically induced transparency, where both the probe and control lasers are resonant with a Fabry-Perot cavity. We demonstrate the precise frequency manipulating of the hybrid optical-atomic resonances, through either temperature or cavity length tuning. In such a system, the control power can be greatly enhanced due to the cavity, and all-optical switching is achieved with a much lower control laser power compared to previous studies. A new theoretical model is developed to describe the effective three-wave mixing process between spin-wave and optical modes. Interesting non-Hermitian physics are predicted theoretically and demonstrated experimentally. Such a doubly-resonant cavity-atom ensemble system without a specially designed cavity can be used for future applications, such as optical signal storage and microwave-to-optical frequency conversion.
