Here is the characterization of the shot noise.
I ended up with two different answers for the shot noise intercept. When I fitted it to Z(2e(i_{dc}+i_{int})^{1/2}, where Z is the transimpedance, i_dc is the measured data, and i_int is the shot noise intercept, I got 0.27mA. When I fit two lines for the input referred noise level and the shot noise, the shot noise intercept is at 0.17mA.
Also, everytime I get more data, I end up with a different answer :(
While I'm at it, I will post the transfer function of the PD.
