Abstract
In this work, a novel smart quenching approach for a Geiger-mode single-photon avalanche diode is proposed. The avalanche photodiode is connected in series with a metallic filamentary resistive switch (MFRS). The hysteresis behavior of the MFRS makes it suitable to operate as a quenching resistor. Initially the MFRS is in the off state and it quenches an avalanche event triggered by an incident photon. After quenching, the MFRS switches to the low-resistance on-state, which reduces the R-C time constant of the recharging process. A sharp avalanche pulse shape, continuous detection, and fast detection speed have been achieved. Our observations are consistent with a model where the MFRS adaptively changes its resistance state from high to low during quenching and recharging.
