Abstract

We present a method for the generation of correlated photon pairs in desired orbital-angular-momentum states using a non-linear silica ring fiber and spontaneous parametric down-conversion. Photon-pair emission under quasi-phase-matching conditions with quantum conversion efficiency 6 × 10(-11) is found in a 1-m long fiber with a thermally induced χ(2) nonlinearity in a ring-shaped core.

摘要

我们提出了一种利用非线性二氧化硅环形光纤和自发参量下转换来产生处于所需轨道角动量态的关联光子对的方法。在具有环形芯且由热诱导χ(2)非线性的1米长光纤中，发现在准相位匹配条件下量子转换效率为6×10^(-11)的光子对发射。
