Temporal and spatial multiplexed infrared single-photon counter based on high-speed avalanche photodiode
We report on a high-speed temporal and spatial multiplexed single-photon counter with photon-number-resolving capability up to four photons. The infrared detector combines a fiber loop to split, delay and recombine optical pulses and a 200 MHz dual-channel single-photon detector based on InGaAs/InP avalanche photodiode. To fully characterize the photon-number-resolving capability, we perform qu...
متن کاملAutomated Characterization of Single-photon Avalanche Photodiode
We report an automated characterization of a single-photon detector based on commercial silicon avalanche photodiode (PerkinElmer C30902SH). The photodiode is characterized by I-V curves at different illumination levels (darkness, 10 pW and 10 μW), dark count rate and photon detection efficiency at different bias voltages. The automated characterization routine is implemented in C++ running on ...
متن کاملHigh-Speed Single-Photon Detection Using 2-GHz Sinusoidally Gated InGaAs/InP Avalanche Photodiode
We report a telecom-band single-photon detector for highspeed quantum key distribution systems. The single-photon detector is based on a sinusoidally gated InGaAs/InP avalanche photodiode. The gate repetition frequency of the single-photon detector reached 2 GHz. A quantum efficiency of 10.5 % at 1550 nm was obtained with a dark count probability per gate of 6.1×10−7 and an afterpulsing probabi...
متن کاملModelling of High Quantum Efficiency Avalanche Photodiode
A model of a low noise high quantum efficiency n+np Germanium Photodiode utilizing ion implantation technique and subsequent drive-in diffusion in the n layer is presented. Numerical analysis is used to study the influence of junction depth and bulk concentration on the electric field profile and quantum efficiency. The performance of the device is theoretically treated especially at the wave-l...
متن کاملExperimental multi-photon-resolving detector using a single avalanche photodiode
There is an increasing need for identifying the number of photons that is contained within a weak light pulse or time interval of a weak cw light field. A device capable of photon-number resolution would contribute both to fundamental research in the area of quantum optics and to more-or-less practical quantum communication systems, such as quantum key distribution schemes [1]. In the former ca...
