Excess Noise Factor
A factor, F, indicating the increase in shot Noise in an Avalanche Photodiode as compared with the ideal multiplier, which is noiseless. The noise, which results from variations in avalanche gains, is significant in detectors made of semiconductors with similar ionization coefficient values for electrons and holes, such as germanium and III-V compound photodiodes.
