SPAD Single-Photon Detection
SiPM Array Saturation
Number of fired microcells for a given incident photon number and PDE, i.e. SiPM saturation.
N_out = N_pix · [1 − e^(−PDE·N_ph / N_pix)]
Fill the inputs from a real part
Every number is read from that part's datasheet entry: peak power and pulse energy as rated, pulse width at the part's rated maximum.
