It appears as if I did not do anything wrong. I just got it confirmed that power is actually squared in the APD, and that I will simply have to deal with the fact that the dynamic range is doubled inside my receiver than outside of it. Perhaps my problem with the inital findings was mostly...

Thanks for the reply, but I thought of that too. But I still have twice the dynamic range (in dB) compared to the dynamic range of the optical input signal.I think I might be on to an explanation: The APD transforms a power to a current. If one considers a grounded load, Zl, connected to a feed...

Hi everyone. I'll describe my setup first, then state my question. I have a receiver chain consisting of the following (where all conversion factors are assumed to be scalar and constant under the conditions in which I use them): 1) An APD (avalanche photodiode): Input: Optical power P1in...
