Polarization entanglement distribution over 50 km in ITU 22 channel in all waveguide geometry
Nishant Kumar Pathak, Bhaskar Kanseri · 2023
We generate indistinguishable photon pairs in an all-waveguide geometry. We use the source to distribute polarization entangled photons spanning 50 km telecom fiber violating Bell-CHSH inequality with S parameter being 2.53 ± 0.003.
