best_APD_gain

ofiber.best_APD_gain(I0, Rload, Idark, x, T)[source]

Return best gain for an avalanche photodiode.

Parameters:

  • I0 – current (A)

  • Rload – load resistance (Ohms)

  • Idark – dark current (A)

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

  • T – Temperature

Returns:

optimal gain (–)
