摘要

为了研究拉盖尔-高斯光束耦合下闭合V型三能级系统的空间相关电磁感应透明，基于密度矩阵理论建立系统哈密顿量与动力学方程，并求得稳态解。进一步分析径向指数、轨道角动量方位指数、失谐以及相对相位对探测光空间吸收分布的调控作用。结果表明，径向指数主要决定吸收在径向上的节点层级；方位指数决定角向对称的模式；失谐可连续调节电磁感应透明窗口的深度与对比度；相对相位能够引起电磁感应透明在横向平面内的可控旋转与重构。研究为结构化光场驱动下的量子干涉调控及空间光信息处理提供了理论依据。

Abstract

To study the spatially correlated Electromagnetically Induced Transparency （EIT） of a closed V-type three-level system under the coupling of Laguerre-Gaussian beams

the system Hamiltonian and dynamical equations were established based on the density matrix theory

and the steady-state solutions were obtained. Further

the influences of the radial index

the azimuthal index of the orbital angular momentum

detuning

and relative phase on the spatial absorption distribution of the probe light were analyzed. The results show that the radial index mainly determines the node hierarchy of the absorption in the radial direction; the azimuthal index determines the angularly symmetric mode; detuning can continuously adjust the depth and contrast of the EIT window; and the relative phase can cause the controllable rotation and reconstruction of the EIT in the transverse plane. This study provides a theoretical basis for the quantum interference control and spatial optical information processing driven by structured light fields.
