Electrical Shot Noise The shot noise generated in the photodetection process is physically due to the “quantum granularity” of the received (and photo converted) optical signal
Optical Receiver Sensitivity Evaluation in Presence of Noise in Digital
The optical receiver adds two types of noise namely thermal noise and shot noise. Since optical amplifiers are based on the principle of stimulated emission, its main contribution to noise is ASE noise.
Optical Receiver Noise
The shot noise and thermal noise are the two fundamental noise mechanisms responsible for current fluctuations in all optical receivers even when the incident optical power P in is constant.
Receiver noise
Noise introduced by the receiver is either signal dependent or signal independent. Signal dependent noise results from the random generation of electrons by the incident optical power. Signal
