We theoretically study the generation of photon pairs via spontaneous four-wave mixing (SFWM) in a liquid-filled microstructured suspended-core optical fiber. We show that it is possible to control the wavelength, group velocity, and bandwidths of the two-photon states. Our proposed fiber structure shows a large number of degrees of freedom to engineer the two-photon state. Here, we focus on the factorable state, which shows no spectral correlation in the two-photon components of the state, and allows the heralding of a single-photon pure state without the need for spectral post-filtering.
我们从理论上研究了通过自发四波混频（SFWM）在充满液体的微结构悬芯光纤中产生光子对的过程。我们表明，控制双光子态的波长、群速度和带宽是可行的。我们提出的光纤结构显示出在设计双光子态方面有大量的自由度。在这里，我们关注可分解态，该态在其双光子分量中没有光谱相关性，并且无需光谱后置滤波就能实现单光子纯态的预示。
