We propose a quasi-M-type atomic system for realizing the electromagnetically induced polarization grating. The results show that, due to the introduced microwave fields, the first-order diffraction efficiency of the probe field can be increased remarkably. Another advantage of the current scheme is that the two polarization components of the probe field can be decoupled through the flexible manipulation of the controlling fields in period and direction, and it can be employed to design polarization beam splitter. Such a polarization-dependent scheme may find important practical applications in classical and quantum information processing.

准M型原子系统中的电磁感应极化光栅

我们提出了一种用于实现电磁感应偏振光栅的准 M 型原子系统。结果表明，由于引入了微波场，可以显着提高探测场的一阶衍射效率。当前方案的另一个优点是，通过对周期和方向控制场的灵活操纵，可以将探测场的两个偏振分量解耦，并可用于设计偏振分束器。这种偏振相关的方案可能会在经典和量子信息处理中找到重要的实际应用。
