Apparatus and method for allowing avalanche photodiode based single-photon detectors to be driven by the same electrical circuit in gated and in free-running modes

摘要

An apparatus and method for allowing avalanche photodiode based single-photon detectors to be driven by the same electrical circuit in gated and in free-running modes is proposed. The high-performance working of all the running modes relies on the capability of tuning the rise-time value of the electrical pulse driver which activates the avalanche photodiode in Geiger mode.
