利用两个正交耦合驻波场，提出了一种在三能级原子系统中实现二维电磁感应交叉光栅的方案。基于电磁感应透明的原理，探测场在两个耦合驻波场的相互作用下发生衍射，形成二维EICG。结果表明，二维EICG的一阶衍射强度与探测场的失谐量和两个耦合驻波场的拉比频率密切相关。研究结果可用于开发用于量子信息处理、量子网络和光学成像的新型光子器件。
By using two orthogonal coupling standing-wave fields, we propose a scheme for a two-dimensional electromagnetically induced cross-grating (EICG) in a four-level tripod-type atomic system. Based on the electromagnetically induced transparency, the probe field will be diffracted and form the two-dimensional EICG through the interaction of the two coupling standing-wave fields. It is shown that the first-order diffraction intensity of the two-dimensional EICG depends observably on the detuning of the probe field and the Rabi frequencies of the two coupling standing-wave fields. The results may be used to develop novel photonic devices for use in quantum information processing, quantum networking and optical imaging.
