ABSTRACT
Polarization-entangled photon pairs in a band around 1550 nm are generated by use of a fiber-optic two-photon interferometer having two periodically poled lithium niobate waveguides. Coincidence measurements are adopted for feedback control, in order to suppress phase drifts in the state of entanglement. Two-photon interference with a visibility of ∼1 (after subtraction of accidental coincidences) is observed over an hour. The visibility including accidental coincidences is ∼0.77.
