Photodiode Introduction. High-speed p-i-n and avalanche photodetectors (photodiodes) use a heavily doped buried layer to greatly limit minority carriers generated by incident light in the buried layers and the substrates of the devices from reaching the cathodes and thus enhances response time while substantially decreasing dark current. Avalanche Photodiode Receiver Performance Metrics ... All avalanche photodiodes generate excess noise due to the statistical nature of the avalanche process. This channel is dif- ferent from the usual optical channel in that the detector output is characterized by a Webb-plus-Gaussian distribution, not a Poisson distribution. The main electrooptical characteristics of the device are presented, showing a remarkably low-noise factor if compared to other CMOS APDs.
