Abstract :
A photon-counting receiver using an Si avalanche photodiode has been constructed. The circuit noise, dark-current noise and excess noise pulses can be discriminated perfectly from the signal pulse; thus a shot-noise-limited receiver sensitivity has been achieved. The dynamic range of the receiver is above 50 dB.
