Space-time entangled photons generated from a continuous-wave parametric downconverter have a well defined sum-frequency despite having individual broad bandwidths. The narrowband frequency correlation that results from this well defined sum-frequency is examined experimentally. The measurements use degenerate, 1.55 [mu]m photon pairs that are also suitable for fiber-based quantum communication protocols. Techniques for optimizing the pair generation rate, the detector and coincidence circuit parameters and the fiber coupling of down-converted light are also presented. A strong frequency correlation is observed using ~0.5 nm bandpass filters to measure the frequencies of entangled photons with >100 nm individual bandwidths.
