摘要/Abstract

摘要： 光学非互易性是实现全光二极管、芯片隔离器等新型光子器件的核心技术, 而这些器件具有高效、稳定、易于集成等特点, 在量子计算和信息处理中尤为关键。本文在均匀冷原子介质中利用一个强耦合场控制一个弱探测场构成三能级Lambda型相干原子系统, 设置耦合场强度随位置线性变化以破坏极化率的空间对称性, 从而实现非互易反射。此外, 进一步考虑了自发辐射相干对探测场非互易反射的调制, 以及耦合场失谐变化对非互易反射的影响。

关键词: 量子相干, 光学非互易性, 自发辐射相干, 非互易反射, 相对相位, 电偶极矩夹角

Abstract: Optical non-reciprocity is the core technology to realize novel photonic devices such as all-optical diodes and chip isolators. These devices are easy to integrate due to their high efficiency and stability, especially in quantum computing and information processing. In this work, we propose a system that the uniformly distributed cold atoms are driven into a three-level Lambda coherent atomic system by a strong coupling field and a weak probe field. In order to achieve the non-reciprocal reflection, the intensity of the coupling field is set to vary linearly with position to destroy the spatial symmetry of susceptibility. In addition, we further consider the modulation of the non-reciprocal reflection in the probe field by spontaneously generated coherence, as well as the influence of coupling field detuning on the non-reciprocal reflection.

Key words: quantum coherence, optical non-reciprocity, spontaneously generated coherence, non-reciprocial reflection, the relative phase, the dipole angle
