Abstract

We report and correct an error in the estimated overall detection efficiencies for signal and idler photons of the waveguide source.

In Section 4, Paragraph 1, Line 14 of our paper [1], there is an error in the estimated overall detection efficiencies ηs, ηi for signal and idler photons, respectively, in our photon-pair coincidence measurement. The estimates of ηs ≃ 1.8% and ηi ≃ 2.8% in [1] did not include the waveguide-to-fiber coupling loss, which was ~50% for each channel. The correct efficiencies should therefore be ηs ≃ 0.9% and ηi ≃ 1.4%.

The efficiency corrections do not affect any of the experimental results and conclusions, including the pair generation rate of 2.0 × 107 pairs/s/mW which was calculated correctly in [1]. We thank Don Schmadel from the University of Maryland, College Park for pointing out the error.
