相干驱动场对光束古斯-汉臣位移的控制

Control of Goos-Hanchen shift of a light beam via a coherent driving field

Li-Gang Wang, Manzoor Ikram, M. Suhail Zubairy

摘要:

本文提出了一种利用相干控制场来控制光束的古斯-汉臣位移的方法,该方法将光场注入到含有二能级原子介质的腔中。研究发现,通过调节控制场的强度和失谐量,可以很容易地控制反射和透射探测光束的横向位移。该方案在不改变腔体结构的前提下,通过适当的控制场条件,可以提高固定入射角下的横向位移(正或负)。

英文摘要:

We present a proposal to manipulate the Goos-Hanchen shift of a light beam via a coherent control field, which is injected into a cavity configuration containing the two-level atomic medium. It is found that the lateral shifts of the reflected and transmitted probe beams can be easily controlled by adjusting the intensity and detuning of the control field. Using this scheme, the lateral shift at the fixed incident angle can be enhanced (positive or negative) under the suitable conditions on the control field, without changing the structure of the cavity.
