When you hit it with a photon, you get one electron of photocurrent, which flows through the load resistance forming a low pass filter with time constant R*24pF. You need the resistor to convert the current into a voltage.

WebbPhotodiodes. The photodiode is a semiconductor device that has a nearly linear relationship of current to received optical power. The easiest way to think of the photodiode is just as a current source, where the current amplitude is a linear function of optical power incident on the photodiode. WebbA photodiode is a device that produces a current which is linear with the input light power. Light at 1550 nm has a frequency of 200 THz (more or less). So the electric field of the signal is E(z ...
