Experimental 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...
متن کاملAn avalanche-photodiode-based photon-number-resolving detector
Avalanche photodiodes are widely used as practical detectors of single photons. Although conventional devices respond to one or more photons, they cannot resolve the number in the incident pulse or short time interval. However, such photon number resolving detectors are urgently needed for applications in quantum computing, communications and interferometry, as well as for extending the applica...
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 کاملNeural Imaging Using Single-Photon Avalanche Diodes
Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...
متن کاملUltra-low noise single-photon detector based on Si avalanche photodiode.
We report operation and characterization of a lab-assembled single-photon detector based on commercial silicon avalanche photodiodes (PerkinElmer C30902SH, C30921SH). Dark count rate as low as 5 Hz was achieved by cooling the photodiodes down to -80 °C. While afterpulsing increased as the photodiode temperature was decreased, total afterpulse probability did not become significant due to detect...
