论文摘要
从理论上讲，我们研究了激光驱动的一维原子链，该链与纳米量波导的指导光学模式相连。可以选择链的周期和激光场的方向，以使发射主要发生到单个引导模式中。我们发现，随着原子数量的增加，荧光激发线的形状变化，最终进行了分裂，为波导介导的全部相互作用提供了证据。值得注意的是，在强驱动波导中的光的强度方面是非古典的，相关的wigner函数具有显着的负效率。我们表明，发射特性和光的非高斯特征都对原子链中的空隙都具有鲁棒性，从而可以通过当今技术对这些效应进行实验研究。我们的结果为新型的纤维耦合量子光源提供了一条途径，也是通过光通过光探测相互作用的原子团体物理学的有趣观点。
We study theoretically a laser-driven one-dimensional chain of atoms interfaced with the guided optical modes of a nanophotonic waveguide. The period of the chain and the orientation of the laser field can be chosen such that emission occurs predominantly into a single guided mode. We find that the fluorescence excitation line shape changes as the number of atoms is increased, eventually undergoing a splitting that provides evidence for the waveguide-mediated all-to-all interactions. Remarkably, in the regime of strong driving the light emitted into the waveguide is non-classical, with a significant negativity of the associated Wigner function. We show that both the emission properties and the non-Gaussian character of the light are robust against voids in the atom chain, enabling the experimental study of these effects with present-day technology. Our results offer a route towards novel types of fiber-coupled quantum light sources and an interesting perspective for probing the physics of interacting atomic ensembles through light.
