Abstract
Provided is a photo detector. The photo detector includes: an avalanche photodiode; a bias circuit supplying a bias voltage to one end of the avalanche photodiode; a detection circuit connected to the other end of the avalanche photodiode and detecting a photoelectric current occurring in the avalanche photodiode; and a coupling capacitor connected to the one end or the other end of the avalanche photodiode and supplying a coupling voltage to drive the avalanche photodiode in a Geiger mode.
