Abstract
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.
Claims8
A single-photon detection apparatus containing a pulse driver, used for setting the avalanche photodiode in Geiger mode, having a tunable rise-time wherein said tunable rise-time pulse driver enables high-performance working of the said single-photon detection in both operating modes:
- gated and free-running modes.
The apparatus of claims wherein the said pulse driver contains at least one chip or ASIC which enables the generation of a tunable stair-step ramp.
Dependencies are inferred from the claim text.
