according to the special requirements of quantum optics experiments, through the optimum design of broadband low noise amplifier circuit, this paper developed a broadband low noise photoelectric detector. We focus on the analysis of the factors affecting the photoelectric detector gain, bandwidth and noise, by a suitable choice of the photodiode, a sampling resistor, feedback resistor and capacitor, the broadband low noise photoelectric detector. Experiments show that, this circuit can be used for broadband low noise quantum communication circuit.
