SpletShot 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.

The average electrical power is given by Pavg,elec=Iph2RL. After subtracting the system thermal noise and the photodetector shot noise, the intrinsic laser diode RIN can be extracted as: scsk a10 class-listSpletlevels will be limited by the shot noise and the APD’s leakage current. Shot noise derives from the random statistical Poissonian fluctuations of the dark current, ID (or signal current). Dark current shot noise (IN(SHOT)) is normally given by iN(SHOT) = (2⋅q⋅B⋅ID) ½, for a PIN detector, where B is the system bandwidth. scsk12 summer learning academySpletMajor noise sources in a photodiode can be categorized as thermal noise, shot noise, and dark current noise.
