An all fiber source of frequency entangled photon pairs
Xiaoying Li, Lei Yang, Xiaoxin Ma +3
We present an all fiber source of frequency entangled photon pairs by using four wave mixing in a Sagnac fiber loop. Special care is taken to suppress the impurity of the frequency…

Fiber based source of photon pairs at telecom band with high temporal coherence and brightness for quantum information processing
Xiaoying Li, Lei Yang, Liang Cui +2
We experimentally demonstrate a bright pulsed source of correlated photon pairs at 1550 nm telecom band by pumping 300 m dispersion shifted fiber with a 4 ps pulse train. We invest…
