We build and test a single-photon detector based on a Si avalanche photodiode Excelitas 30902SH thermoelectrically cooled to −100 ∘ C. Our detector has dark count rate below 1 Hz, 500 μ m $500\ \mu\mathrm{m}$ diameter photosensitive area, photon detection efficiency around 50%, afterpulsing less than 0.35%, and timing jitter under 1 ns. These characteristics make it suitable for long-distance free-space quantum communication links, which we briefly discuss. We also report an improved method… Expand

Germanium avalanche photodiodes (APD's) working biased above the breakdown voltage detect single optical photons in the near-infrared wavelength range, and it is shown that some selected APD's achieve an 85-ps time resolution in the detection of optical photons at a 1.3-µm wavelength, which corresponds to a timing-equivalent bandwidth of 1.8 GHz.
