论文摘要
我们在实验上证明了一种较窄的光谱带宽约795 nm的光谱单光子的光谱压缩方案，该光谱通过在冷RB-87原子云中通过四波混合而产生。该方案基于不对称腔作为分散介质和简单的二元相调节剂，并且原则上可以没有任何光学损失。我们观察到从20.6 MHz到小于8 MHz的压缩，几乎与相应的原子过渡匹配。
We experimentally demonstrate a spectral compression scheme for heralded single photons with narrow spectral bandwidth around 795 nm, generated through four-wave mixing in a cloud of cold Rb-87 atoms. The scheme is based on an asymmetric cavity as a dispersion medium and a simple binary phase modulator, and can be, in principle, without any optical losses. We observe a compression from 20.6 MHz to less than 8 MHz, almost matching the corresponding atomic transition.
