摘　　要：量子点单光子探测器具有可保持测试信号完整性、理论量子效率高、工作电压低等优点,同时具有室温单光子探测的潜力,最近得到了广泛的研究。文章介绍了基于三种不同形式量子点的单光子探测器,讨论了它们的工作原理,对比了各自的性能和参数,总结了各种器件的特点,说明了自组织量子点单光子探测的优越性能。The single photon detector based on quantum dots（QD） is widely researched due to its advantages such as the potential of single photon detection under room temperature, the ability to maintain the integrity of the detected signal, high theoretical quantum efficiency and the low working voltage. In this paper, three different types of single photon detectors based on quantum dots and their working principles are reviewed. Also discussed are the parameters and characteristics of the detectors. The excellent performance of self-assembly quantum-dot-based single photon detector is explained.
