利用硅光电倍增管和Time Tagger Ultra探测多个光子

Mon, 03 Jun 2019 13:05:44 +0000

硅光电倍增管（SiPM）在高精度单光子定时测量中具有很多应用场景，包括LIDAR、生物光子学和正电子发射断层扫描。它们探测闪烁事件中光子数量的能力是获得低噪声、高保真信号的关键。以往，从探测器输出脉冲中提取光子数是通过快速ADC或多级模拟鉴别器（过阈时间法time-over-threshold approach）来实现的。Swabian Instruments与KETEK GmbH一起开发了一种新的方法，仅使用单个输入阈值并依靠信号脉冲持续时间。通过检测上升沿和下降沿，我们会获得一个明显的脉冲宽度，该脉宽直接编码光子数。这种测量能力是由Swabian Instruments的Time Tagger Ultra实现的。其高定时精度可精确表征探测器的定时抖动。

我们的脉冲宽度过滤法能够解析光子数，并同时为探测到的光子提供精确的定时信息。利用Time Tagger的流架构，同时读取光子数量和定时信息，显示了Time Tagger及其软件引擎的多功能性。事实证明，Time Tagger是多光子探测器表征以及正电子发射断层扫描（PET）等各种应用开发中的有力工具。

单光子随机采样可轻松、精确地测量光信号，最高可达THz级别

Wed, 16 May 2018 13:05:44 +0000

单光子计数已在量子技术中得到了广泛的应用，例如量子感应、量子信息和量子通信。最近有人提出，低抖动单光子探测器可用于实现带宽远远超过100 GHz的光学随机取样范围，这是现有测量仪器无法达到的。该技术可用于研究锁模激光器和下一代电光设备，如EOM和VCSEL。此外，光学采样技术不需要在金属线上传输极快的电信号，后者会导致信号失真程度增加和高带宽信号衰减。在Swabian Instruments的应用注释中，我们进行了一次原理证明演示测量，并描述了使用单光子雪崩探测器（SPAD）和超导纳米线单光子探测器（SNSPD）的SFP+模块。随着当前SNSPD的抖动达皮秒级别，该方法可保证测量带宽远超100 GHz。

我们最后使用的是Time Tagger加一个C＃应用程序，非常容易实现。仅需几行代码，我们就可以分析单光子源的性能。我会推荐Time Tagger——尤其是用于你自己的控制软件。

使用Time Tagger API（Python，Matlab，C＃等），只需多加两行代码就可使用多起点/多终点分析来获取、累积和分析数据:

Line 1: initialize the measurement
 Ch, Ch, window in ps
> correlation = Correlation(timetagger, 0, 1, 200)

Line 2: evaluate the integrated data
> histogram = correlation.getData()

通过这种非常简单的数据采集和评估方式，我们可以看到Swabian Instruments提供的软件定义数据采集所具备的优势。
