Avalanche Photodiode Receiver Performance Metrics

TECHNICAL NOTE: V803 Avalanche Photodiode Receiver Performance Metrics Introduction The following note overviews the calculations used to assess the noise equivalent power (NEP), noise equivalent input (NEI), and signal to noise ratio (STN) Performance of Avalanche photodiodes (APDs) and APD photoreceivers. Shown are the effects of the APD s effective ionization constant, keff, which characterizes the noise of the Avalanche process. Background APDs are photodetectors that can be regarded as the semiconductor analog of photomultiplier tubes (PMTs). One important difference is that APDs don t have a photocathode that is physically separate from their current gain medium, and so they typically use primary photocarriers more efficiently than PMTs.
