摘要

我们使用两个垂直的周期性极化磷酸钛钾晶体(KTP)在单一空间模式下有效地产生频率非简并的偏振纠缠光子。该光源结构紧凑,价格低廉,适合远距离光纤量子通信。

Bright source of polarization-entangled photons using periodically poled potassium titanyl phosphate (KTP)
We used two perpendicular crystals of periodically-poled potassium titanyl phosphate (KTP) to efficiently generate frequency-nondegenerate, polarization-entangled photons in a single spatial mode. The source is compact, inexpensive, and suitable for long-distance fiber-based quantum communication.
