Beschreibungen/Notizen

• A free-running single-photon detector for 1.06 μ m wavelength based on an InGaAsP/InP single-photon avalanche diode is presented. The detector incorporates an ultra-fast active-quenching technique to greatly lessen the afterpulsing effects. An improved method for avalanche characterization using electroluminescence is proposed, and the performance of the detector is evaluated. The number of avalanche carriers is as low as 1.68 × 10 6 , resulting in a low total afterpulse probability of 4% at 233 K, 10% detection efficiency, and 1 μ s hold-off time.
