本文研究了双折射光子晶体光纤（PCF）中四波混频产生的光子光谱特性的剪裁。其目的是产生固有的窄带光子，从而实现高的非经典干涉可见度，并产生高保真纠缠，而不需要任何光谱滤波，从而提高有效的检测效率。我们表明，未经过滤的Hong-Ou-Mandel干涉的77%之间的光子从相同的PCF和80%之间的单独的源。我们比较这些实验的PCF建模的结果和分析光子纯度。
In this paper, we study the tailoring of photon spectral properties generated by four-wave mixing in a birefringent photonic crystal fibre (PCF). The aim is to produce intrinsically narrow-band photons and hence to achieve high non-classical interference visibility and generate high-fidelity entanglement without any requirement for spectral filtering, leading to high effective detection efficiencies. We show unfiltered Hong-Ou-Mandel interference visibilities of 77% between photons from the same PCF and 80% between separate sources. We compare results from modelling the PCF to these experiments and analyse photon purities.
