我们展示了硅光倍增器(SiPM)的快速计数和多光子探测能力。在快速计数模式下，我们能够探测到相隔仅2.3 ns的两个连续光子，对应于430 MHz。对波长为532 nm的小光强的计数效率约为16%，在T=-5℃时的暗计数率为52 kHz。在多光子探测模式下，我们发现对不同数目的同时探测到的光子有很好的信号分辨能力。(C)2007年美国光学学会。
We demonstrate fast counting and multiphoton detection abilities of a Silicon Photo Multiplier (SiPM). In fast counting mode we are able to detect two consecutive photons separated by only 2.3 ns corresponding to 430 MHz. The counting efficiency for small optical intensities at lambda = 532 nm was found to be around 16% with a dark count rate of 52 kHz at T= -5 degrees C. Using the SiPM in multiphoton detection mode, we find a good signal discrimination for different numbers of simultaneously detected photons. (C) 2007 Optical Society of America.
