摘要
分析了SAGM-APD单光子探测器暗电流产生的机理;得出工作温度和偏置电压是影响SAGMInGaAs/InP单光子探测器探测性能的重要因素。通过实验,分析了三种APD在不同温度下暗电流、光电流与偏置电压的关系曲线,得出一些结论。
The mechanism of dark current in InGaAs/InP single photon detection is analyzed to show the performance affected by operation temperature and biased voltage. characteristics measured at different temperature in three avalanche photodiode operated in Geiger mode for of InGaAs/InP avalanche photodiode that is largely Photo current-Voltage and Dark current-Voltage single photon detectors are studied and valuable conclusions are reached.
