The shot noise

WebThe ASE power can be related to the noise figure (NF) of the amplifier, which is defined as the signal-to-noise ratio (SNR) corresponding to the shot noise of the signal at the input divided by SNR at the output. The NF is a measure of the degradation of the optical signal by the ASE noise added by the amplifier.

WebThe amount of shot noise inherent in the signal is a function of the amount of signal—the more signal you have, the smaller the fraction of the signal comes from shot noise (see … Shot noise or Poisson noise is a type of noise which can be modeled by a Poisson process. In electronics shot noise originates from the discrete nature of electric charge. Shot noise also occurs in photon counting in optical devices, where shot noise is associated with the particle nature of light. See more In a statistical experiment such as tossing a fair coin and counting the occurrences of heads and tails, the numbers of heads and tails after many throws will differ by only a tiny percentage, while after only a few throws outcomes … See more Electronic devices Shot noise in electronic circuits consists of random fluctuations of DC current, which is due to electric current being the flow of discrete charges (electrons).
