The shot noise
WebIn general, the term shot noise is applied to any noise component reflecting a similar statistical variation, or uncertainty, in measurements of the number of photons collected during a given time interval, and some references use that term in place of photon noise in discussions of CCD noise sources. WebShot noise (PMT) (CCD) 1 . Shot noise Photodiodes (PD), photomultiplier tubes (PMT) and charge coupled devices (CCD) all work on the basic principle that when photons strike …

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.
