Abstract :
Measurements of the statistical distributions of excess noise as a function of avalanche gain and incident optical power are reported for SAGM avalanche photodiodes. The observed distributions are not Gaussian, but exhibit a `high-side¿ tail which has consequences for the performance of these APDs in optical receivers.
