Waveguide-integrated superconducting nanowire single photon detectors — Simone Ferrari1,2, •Fabian Beutel1,2, and Wolfram Pernice1,2 — 1University of Münster, Institute of Physics, Germany — 2University of Münster, CeNTech - Center for Nanotechnology, Germany
Nanophotonic technology empowers the realization of low-loss, small-footprint and scalable hybrid architectures for generating, manipulating and detecting single photons [1]. Thanks to their high efficiency, wide optical detection bandwidth, fast response and low timing uncertainty, waveguide-integrated superconducting nanowire single photon detectors represent a catalyst for the development of quantum technology and life science. We show our recent achievement on the integration of single photon detector devices to complex nanophotonic architectures. We demonstrate the realization of a fully integrated device with electrically driven single photon emitters and single photon detectors [2]. To overcome the inability for superconducting detectors to resolve photon energy, we integrate eight detectors in a multi-channel arrayed waveguide grating realizing a fully integrated single-photon spectrometer [3] and, as further improvement, we demonstrate an on-chip quantum limited heterodyne detection technique with ultra-high spectral resolution [4].
