An avalanche photodiode is a semiconductor device. It is a very similar structure to that of PIN or PN photodiode types. These diodes are specially designed to work in the reverse breakdown area. In an avalanche photodiode is basically two terminal namely anode and cathode. It is similar or looks like Schottky photodiode. Avalanche multiplication of the holes and electrons created by photon impact. Here is some application of avalanche photodiode.
