论文摘要
本教程论文的目的是通过光纤中的自发四波混合（SFWM）过程介绍光子对生成的广泛概述。光纤技术的进展意味着，今天我们可以使用各种类型的纤维，这与SFWM使用两个泵场的事实意味着在可能的可能的光子对属性中确实具有显着的多功能性。我们讨论了频率，横向模式和极化程度的相互作用是如何通过纤维分散与后两种相关的自由度如何导致在单个自由度下具有有趣的构造特性，并且还允许在自由度组合中混合和超级纠缠。该教程涵盖了光子对可分解性，频率可调性和SFWM带宽控制，频率非分级和反传播泵的效果的方法，以及表征光纤中产生的光子对的方法。
The purpose of this tutorial paper is to present a broad overview of photon-pair generation through the spontaneous four wave mixing (SFWM) process in optical fibers. Progress in optical fiber technology means that today we have at our disposal a wide variety of types of fiber, which together with the fact that SFWM uses two pump fields, implies a truly remarkable versatility in the resulting possible photon-pair properties. We discuss how the interplay of the frequency, transverse mode, and polarization degrees of freedom, the first linked to the latter two through fiber dispersion, leads to interesting entanglement properties both in individual degrees of freedom and also permitting hybrid and hyper entanglement in combinations of degrees of freedom. This tutorial covers methods for photon pair factorability, frequency tunability, and SFWM bandwidth control, the effect of frequency non-degenerate and counter-propagating pumps, as well methods for characterizing photon pairs generated in optical fibers.
