Alexander N. Poddubny, Dragomir N. Neshev, Andrey A. Sukhorukov

摘要:

本文综述了超颖表面非线性纳米谐振器产生量子光的最新进展。超颖表面的非线性纳米谐振器既可以作为量子态的源,又可以作为纳米天线对发射出的光子进行整形。我们概述了任意非线性光子结构中自发光子对产生的一般量子理论,包括纳米谐振器和超颖表面,它提供了一个明确的解析解的光子状态表示通过经典的格林函数。我们制定的量子光子对的产生和经典的和频过程在非线性介质之间的对应关系,并讨论其在各种情况下,包括波导电路和纳米结构的应用。我们还讨论了第一个实验结果表明在一个单一的非线性纳米天线的光子对产生。

英文摘要:

We review the latest advances in the generation of quantum light with nonlinear nanoresonators in metasurfaces, which act both as sources of quantum states and nanoantennas shaping the emitted photons. We outline a general quantum theory of spontaneous photon-pair generation in arbitrary nonlinear photonic structures, including nanoresonators and metasurfaces, which provides an explicit analytical solution for the photon state expressed through the classical Green function. We formulate the correspondence between the quantum photon-pair generation and classical sum-frequency process in nonlinear media, and discuss its application in various contexts, including waveguide circuits and nanostructures. We also discuss the first experimental results demonstrating photon-pair generation in a single nonlinear nanoantenna.
