摘要: 单光子探测技术对于量子密钥分配乃至量子通信有重要的意义。针对单光子雪崩光电二极管(SPADs)的单光子量子效率(SPQE),提出了一种严格的数学模型。模型适用于工作波长为1.3和1.5um的In052Al048As、InP倍增层和In052Al048As-InP异质结倍增层的SPADs。模型作为器件结构、工作电压、倍增层材料的函数,可用来优化SPQE,进而评估和优化盖革模式下APDs的性能。

Abstract: Single-photon detection technology has important significance for quantum key distribution and even quantum communication. According to single-photon quantum efficiency(SPQE)of single-photon avalanche photodiodes(SPADs), a strict mathematical model was proposed,Theoretic Criterion for the Performance of Single Photon Avalanche Photodiodes. The model is suitable for SPADs with In052Al048As or InP multiplication layer as well as In052Al048As-InP heterojunction multiplication layer for operating wavelengths of 1.3 and 1.5um. As the function of the device structure, operating voltage, and multiplication layers materials, the model can be used to optimize SPQE, furthermore evaluate and optimize the performance of APDs in Geiger mode.

Key words: optoelectronics, single-photon quantum efficiency, avalanche probability, dark count, avalanche photodiodes
