在本文中,我们提出了一个稳定的单光子探测方法基于硅雪崩光电二极管(硅雪崩二极管)在盖革模式具有较大的温度变化范围内操作。通过精确的温度传感和直流(DC)电压补偿,单光子探测器可以稳定工作在盖革模式from-40°C至35 C°具有几乎恒定的雪崩增益。它为单光子探测在全天候条件下的户外作业提供了一种解决方案。
In this paper, we present a stable single-photon detection method based on Si-avalanche photodiode(Si-APD) operating in Geiger mode with a large temperature variation range. By accurate temperature sensing and direct current(DC) bias voltage compensation, the single-photon detector can work stably in Geiger mode from-40 °C to 35 °C with an almost constant avalanche gain. It provides a solution for single-photon detection at outdoor operation in all-weather conditions.
