论文摘要
通过为颜色擦除开发一种“两晶”方法,我们可以扩大色度干涉量的范围,以包括光光子的频率差,其频率差在400 nm到4500 nm波长范围之外,这是PPLN晶体的通带。我们通过观察1064.4 nm和1063.6 nm的源之间的干扰模式在实验上证明了这种可能性,对应于约200 GHz的频率差。
By developing a `two-crystal' method for color erasure, we can broaden the scope of chromatic interferometry to include optical photons whose frequency difference falls outside of the 400 nm to 4500 nm wavelength range, which is the passband of a PPLN crystal. We demonstrate this possibility experimentally, by observing interference patterns between sources at 1064.4 nm and 1063.6 nm, corresponding to a frequency difference of about 200 GHz.
