摘要
A method and apparatus for providing non-linear, passive quenching of avalanche currents in Geiger-mode avalanche photodiodes (APDs) is provided. A non-linear, passive, current-limiting device is connected in series with the APD and a bias source. The non-linear, passive, current-limiting device rapidly quenches avalanche currents generated by the APD in response to an input photon and resets the APD for detecting additional photons, using a minimal number of components. The non-linear, passive, current-limiting device could comprise a field-effect transistor (FET), as well as a junction FET (JFET) a metal-oxide semiconductor FET (MOSFET), or a current-limiting diode (CLD) connected in series with the APD and the bias source.
