High photon detection efficiency InGaAs/lnP single photon avalanche diode at 250 K
文献摘要：
Planar semiconductor InGaAs/lnP single photon avalanche diodes with high responsivity and low dark count rate are preferred single photon detectors in near-infrared communication.However,even with well-designed structures and well-con-trolled operational conditions,the performance of InGaAs/lnP SPADs is limited by the inherent characteristics of avalanche pro-cess and the growth quality of InGaAs/lnP materials.It is difficult to ensure high detection efficiency while the dark count rate is controlled within a certain range at present.In this paper,we fabricated a device with a thick InGaAs absorption region and an anti-reflection layer.The quantum efficiency of this device reaches 83.2％.We characterized the single-photon performance of the device by a quenching circuit consisting of parallel-balanced InGaAs/lnP single photon detectors and single-period sinus-oidal pulse gating.The spike pulse caused by the capacitance effect of the device is eliminated by using the characteristics of parallel balanced common mode signal elimination,and the detection of small avalanche pulse amplitude signal is realized.The maximum detection efficiency is 55.4％with a dark count rate of 43.8 kHz and a noise equivalent power of 6.96×10-17 W/Hz1/2 at 247 K.Compared with other reported detectors,this SPAD exhibits higher SPDE and lower noise-equivalent power at a higher cooling temperature.
