Enrico Pomarico, Bruno Sanguinetti, Rob Thew, Hugo Zbinden

摘要:

大动态范围室温光子数分辨探测器对于测量极低光强和分析多光子量子态是非常有用的。在本文中,我们提出了一个PNR检测器的基础上转换(UC)的电信信号到可见光波长和其检测的热电冷却的多像素硅雪崩光电二极管(APD),也被称为硅光子倍增器(SiPM)。效率达到4%,输入相干态的泊松统计保持到大约20个同时检测。估计对检测信号的串扰影响,以便正确校准检测器。该方案可以在可见光谱窗口以上的任意波长处使用,并具有适当的上转换。

英文摘要:

Large dynamic range room temperature photon number resolving (PNR) detectors can be very useful for measuring very low light intensities and for analyzing multiphoton quantum states. In this paper we present a PNR detector based on the up-conversion (UC) of telecom signal into visible wavelength and on its detection by a thermoelectrically cooled multi-pixel silicon avalanche photodiodode (APD), also known as Silicon Photon Multiplier (SiPM). An efficiency of 4% is attained and the poissonian statistics of input coherent states is maintained up to approximately 20 simultaneous detections. The cross-talk effects on the detected signal are estimated in order to properly calibrate the detector. This scheme can be used at arbitrary wavelengths above the visible spectral window with appropriate up-conversion.
