Abstract

Here, we investigate the structured superluminal and subluminal light propagation in the medium generated through a five-level atomic configuration controlled by a tiny probe and multiple of the control field. The absorption and dispersion are altered with the topological charges of control fields. The maxima and minima of absorption and corresponding normal/anomalous dispersion region are enhanced according to the \(2\ell\) condition in the medium. The group index differs in the domain of \(-15000\le n_g \le 17500\) in the position ranges of \(-1\mu m\le x,y \le 1 \mu m\). The corresponding velocity of the envelope wave \(v_{g}\) is calculated by \(c/n_g\). The subluminal and superluminal maximum and minimum regions are also enhanced with the \(2\ell\) condition in the medium. The modified work of this manuscript is useful for storage devices, imaging coding, and designing technology.

五能级原子介质中结构光超光速和亚光速传播的相干产生
在这里,我们研究了结构超光速和亚光速光在由一个微小探针和多个控制场控制的五能级原子组态产生的介质中的传播。吸收和色散随控制场的拓扑电荷而改变。根据介质中的\(2\ell\)条件,增大了吸收的最大值和最小值以及相应的正色散区和反常色散区。在\(-1\mu m\le x,y \le 1 \mu m\)的位置范围内,组索引在\(-15000\le n_g \le 17500\)的域中不同。相应的包络波速度\(v_{g}\)由\(c/n_g\)计算。在介质\(2\ell\)条件下,光下和光上最大值和最小值区域也增强。本文的修改工作对存储器件、成像编码和设计技术有一定的指导意义。
