Abstract: Single-photon detector apparatus comprising a large core optical fiber with a core diameter larger than 8 µm, a small core optical fiber with a core diameter smaller or equal to 5 µm, a taper between the large core optical fiber and the small core optical fiber, a superconducting nanowire having a surface area configured to receive all photons emitted from the small core optical fiber and cost effective and high yield method for manufacturing such.
