Abstract
We present an azimuthal phase-dependent scheme to study the spatially dependent electromagnetically induced transparency (EIT) and the generation of spatial light in a closed-loop four-level Y-type system. A structured control beam and a microwave (MW) field are adopted in the closed-loop structure. Interestingly, the weak non-vortex probe beam responses explicitly depend on the orbital angular momentum (OAM) of the control beam along with the MW-assisted quantum interference. The regions of spatially dependent EIT are demonstrated at different azimuthal angles. It is found that the intensity of the structured control beam and the relative phase arising out of the beams participating in the closed-loop can be used as the controlling knobs to tailor the shape and the angular location of the spatially dependent EIT.
我们提出了一种与方位角相位相关的方案,用于研究闭环四级 Y 型系统中与空间相关的电磁诱导透明(EIT)和空间光的产生。闭环结构中采用了结构化控制光束和微波(MW)场。有趣的是,微弱的非涡旋探针光束响应明确取决于控制光束的轨道角动量(OAM)以及微波辅助量子干涉。不同方位角的空间依赖性 EIT 区域得到了证实。研究发现,结构化控制光束的强度和参与闭环的光束产生的相对相位可用作控制旋钮,以调整空间相关 EIT 的形状和角度位置。
期刊介绍:
Published twice-monthly (24 issues per year), Journal of Physics B: Atomic, Molecular and Optical Physics covers the study of atoms, ions, molecules and clusters, and their structure and interactions with particles, photons or fields. The journal also publishes articles dealing with those aspects of spectroscopy, quantum optics and non-linear optics, laser physics, astrophysics, plasma physics, chemical physics, optical cooling and trapping and other investigations where the objects of study are the elementary atomic, ionic or molecular properties of processes.
