PRESENTED BY:- Combined with … - Avalanche photodiode . Avalanche Photodetector (APD) Principles Ionization coefficient αe≈αhIonization coefficient αe>> αh The avalanche process is asymmetric (i.e., the probability for initiating an avalanche is usually greater for one type of carrier than for the other). When photons of energy greater than 1.1 eV hit the diode, electron-hole pairs are created. The APD will remain in a metastable state until a photon arrives and generates an avalanche (Point B).
