Silicon Quantum Photonic Integrated Circuits Comprising Superconducting Nanostripe Single-Photon Detectors

We report on design, fabrication, and characterization of silicon quantum photonic integrated circuits comprising superconducting nanostripe single-photon detectors integrated with dielectric optical waveguides. In order to enhance absorption of photons by the superconducting nanostripes, the detectors are located directly on the dielectric waveguide core.
