1. A photodetector, comprising:
a first electrical port;
a second electrical port;
an avalanche photodiode comprising a first terminal and a second terminal, the second terminal of the avalanche photodiode is electrically coupled to the second electrical port; and
an adaptive photocurrent quenching resistor electrically coupling the first terminal to the first electrical port,
wherein:
the adaptive photocurrent quenching resistor comprises a dielectric layer with reversible bias-voltage dependent resistivity.
