Abstract: | InGaAs/InP avalanche photodiode (APD) is used in the design of single�photon detector of quantum communication. Single�photon detector bias generation circuit, single�photon signal amplification circuit, single�photon signal detection circuit and temperature control module are designed. The sensitivity of detection systems is improved to some extent by using high�precision pre�amplifier OP37 and sophisticated comparator AD8561, as well as safer and more precise temperature controller chip MAX1978. |
