shot_noise

ofiber.shot_noise(I0, Idark, bandwidth, M=1, x=0)[source]

Return the noise current associated with shot/poisson noise.

Parameters:

  • I0 – current (A)

  • Idark – dark current (A)

  • bandwidth – bandwidth (Hz)

  • M – APD Gain factor (–)

  • x – excess noise (0.3 for Si, 0.7 for InGaAs, 1.0 for Ge APDs)

Returns:

shot_noise (A)
