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
