腔原子极化激元的弱光开关

Low-intensity light switching of cavity-atom polaritons

Yifu Zhu

摘要:

本文分析了由多个三能级原子组成的腔QED系统中的全光开关方案。从自由空间耦合到原子的控制激光在耦合腔-原子系统中引起量子干涉,并实现腔-原子极化激元的全光开关。当腔被调谐到远离原子共振时,腔-原子极化激元由几乎纯的光子激发组成,因此该方案可用于低光强下的光子开关。

英文摘要:

I analyze an all-optical switching scheme in a cavity QED system consisting of multiple three-level atoms confined in a cavity mode. A control laser coupled to the atoms from free space induces quantum interference in the coupled cavity-atom system and performs all optical switching of the cavity-atom polaritons. When the cavity is tuned far away from the atomic resonance, the cavity-atom polariton consists of nearly pure photonic excitation and then the scheme can be used for photon switching at low light intensities.
