Abstract

We study the Goos-Hänchen shift (GHS) of a reflected light beam from a cavity containing a double-[Formula: see text] atomic medium that is bounded by two glass slabs. Applying both coherent and incoherent fields to the atomic medium leads to positive and negative controllability of GHS. For some specific values of the parameters of the system, the amplitude of the GHS becomes large, namely, in the order of [Formula: see text] times the wavelength of the incident light beam. These large shifts are found at more than one angle of incidence with a wide range of parameters of the atomic medium.

摘要

我们研究了由包含双[Formula: see text]原子介质的腔反射光的古斯-汉欣位移（GHS），该介质由两个玻璃平板限制。将相干和非相干场应用于原子介质会导致 GHS 的正、负可控性。对于系统参数的某些特定值，GHS 的幅度变得很大，即在入射光束波长的[Formula: see text]倍数量级。这些大的位移出现在多个入射角，并且原子介质的参数范围很宽。
