论文摘要
我们演示了一个原子法拉第二分束分离器,适合于在原子源中与泵退化的四波混合的空间分离信号和惰轮场。通过旋转一种模式的极化平面$ 90^{\ circ} $相对于另一个模式,随后的两极分化束分配器将两个频率分开,它们仅差异为13.6 GHz,并抑制了$(-26.3 \ pm0.1)$(-26.3 \ pm0.1)$和$(-21.2.2 \ pm0.1)$ db in 9 and n n n n in 9 and 9 and n in 9 and n n n in 9 and 9 and a n n n n in 9 and 9 and 9 and n n 9 ny 9;该技术避免了需要使用四波混合模式的空间分离,从而为波导实验中的过程效率打开了大门。作为原理证明,我们通过$^{87} $ rb中的四波混合产生光,并加载到空心的光子光子晶体纤维中,并与原子法拉第(Faraday)二分法梁分离器接口。
We demonstrate an atomic Faraday dichroic beam splitter suitable to spatially separate signal and idler fields from pump degenerate four-wave mixing in an atomic source. By rotating the plane of polarization of one mode $90^{\circ}$ with respect to the other, a subsequent polarizing beam splitter separates the two frequencies, which differ by only 13.6 GHz, and achieves a suppression of $(-26.3\pm0.1)$ and $(-21.2\pm0.1)$ dB in the two outputs, with a corresponding transmission of 97 and 99 %. This technique avoids the need to use spatial separation of four-wave mixing modes and thus opens the door for the process efficiency to be enhanced in waveguide experiments. As a proof-of-principle we generate light via four-wave mixing in $^{87}$Rb loaded into a hollow-core photonic crystal fiber and interface it with the atomic Faraday dichroic beam splitter.
