Abstract
We create pairs of non‐degenerate time‐bin entangled photons at telecom wavelengths with ultra‐short pump pulses. Entanglement is shown by performing Bell kind tests of the Franson type with visibilities of up to 91 time‐bin entanglement can easily be protected from decoherence as encountered in optical fibers, this experiment opens the road for complex quantum communication protocols over long distances.
