Integrable optical-fiber source of polarization-entangled photon pairs in the telecom band
Integrable optical-fiber source of polarization-entangled photon pairs in the telecom band
We demonstrate an optical-fiber-based source of polarization-entangled photon pairs with improved quality and efficiency, which has been integrated with off-the-shelf telecom components and is, therefore, well suited for quantum communication applications in the 1550-nm telecom band. Polarization entanglement is produced by simultaneously pumping a loop of standard dispersion-shifted fiber with …
