In this article we propose a four-level rubidium (Rb 87 ) atomic system for observing interesting features of polarization state rotation in a fast light medium. We investigate spontaneously generated coherence (SGC) for a spinning medium. We show how SGC can affect different spectral profiles of the polarization state and images in this suggested model. We observe a 0.5 radian rotation and 2.5 microsecond time advancement in our proposed system. Our precise results will provide a new platform for researchers in quantum optics due to its applications in image coding, telecommunications and cloaking technology.

在自旋快光介质中通过自发产生的相干性的偏振态和图像旋转

在本文中，我们提出了一种四能级（（Rb 87）原子系统，用于观察快速光介质中偏振态旋转的有趣特征。我们调查了纺丝介质的自发产生的相干性（SGC）。我们在此建议的模型中显示了SGC如何影响偏振态和图像的不同光谱轮廓。我们在我们提出的系统中观察到0.5弧度旋转和2.5微秒时间提前。由于其在图像编码，电信和隐身技术中的应用，我们的精确结果将为量子光学研究人员提供一个新的平台。
