Keywords:Silicon avalanche avalanche photodiode

We report on the frequency-up-conversion single-photon detector with 45% photon detection efficiency at telecom-wavelength. Using a high-efficiency gated silicon avalanche photodiode, the very high photon detection efficiency was achieved with low noise counts.
