Ultralow-Loss Integrated Photonics Enables Bright, Narrowband, Photon-Pair Sources
We demonstrate a bright, narrowband, photon-pair source with ultralow-loss Si 3 N 4 waveguides fabricated using a standard CMOS foundry process. The photon-pair source achieves narrow linewidth comparable to atomic transitions, and record brightness for silicon photonics.
