论文摘要
我们确定光线通过平面原子阵列的传输，超出了低光强度的极限，该阵列在平均场状态下显示出光学双重性。我们开发了一种描述固有的光学双重性的理论，该理论纯粹由自由空间中的谐振偶极 - 偶极相互作用支持，表明双旋光灯如何表现出强大的和弱的单元响应，以及它们如何依赖于潜在的低光强度集体集体激发特征性特征性。该理论的相似性与腔中的光学双重性相似，而原子之间的复发光散射则在腔体镜子的作用上。我们的数字和分析估计值显示，阵列的灭绝，反射率和群体延迟存在急剧变化，入射光完全熄灭至远远超出低光强度极限的临界强度。我们的分析为集体非线性光学元件提供了一种合作响应密集的原子集合的方式。
We determine the transmission of light through a planar atomic array beyond the limit of low light intensity that displays optical bistability in the mean-field regime. We develop a theory describing the intrinsic optical bistability, which is supported purely by resonant dipole-dipole interactions in free space, showing how bistable light amplitudes exhibit both strong cooperative and weak single-atom responses and how they depend on the underlying low light intensity collective excitation eigenmodes. Similarities of the theory with optical bistability in cavities are highlighted, while recurrent light scattering between atoms takes on the role of cavity mirrors. Our numerics and analytic estimates show a sharp variation in the extinction, reflectivity, and group delays of the array, with the incident light completely extinguished up to a critical intensity well beyond the low light intensity limit. Our analysis paves a way for collective nonlinear optics with cooperatively responding dense atomic ensembles.
