标题： Rectification of light in the quantum regime

摘要： 实现集成光学电路的一个缺失要素是起光学二极管作用的整流器件。 一个基于一对强耦合到一维波导的两能级原子的提议在半经典研究中表现出有前景的行为 [Fratini 等，Phys. Rev. Lett. 113, 243601 (2014)]。 我们在全量子 regimes 的研究显示，在这种器件中，整流是一种纯粹的多光子效应。 对于处于相干态的输入场，在其中一个原子被激发而另一个未被激发的功率范围内，整流可达到$70\%$。 显示英文摘要

摘要： One of the missing elements for realising an integrated optical circuit is a rectifying device playing the role of an optical diode. A proposal based on a pair of two-level atoms strongly coupled to a one-dimenisonal waveguide showed a promising behavior based on a semi-classical study [Fratini et al., Phys. Rev. Lett. 113, 243601 (2014)]. Our study in the full quantum regime shows that, in such a device, rectification is a purely multi-photon effect. For an input field in a coherent state, rectification reaches up to $70\%$ for the range of power in which one of the two atoms is excited, but not both.
