Infrared time correlated single photon spectroscopy system for characterization of quantum light sources

该应用是用于两个红外光电探测器和相关的电子器件，它们一起使单个光子事件能够以优于1纳秒的时间分辨率被“时间标记”。 这种类型的检测系统是必需的，以便表征在电磁光谱的红外部分中发射的来自样品的光子的统计。 申请人有几个资助的研究项目，涉及红外线中的新型光源的开发，并且需要所要求的设备，以便量化表征这些新光源的独特特性。 该研究的主要目标之一是展示本质上是量子力学的光源，并且可以集成到硅晶片上制造的光学电路中。 这种光源对于基于量子力学原理的未来信息技术（例如完全安全的信息交换，以及可能有一天的量子计算）将是重要的。 加拿大几乎没有相关的基础设施：据申请人所知，渥太华的NRC是唯一一个拥有与这里所要求的设备类似的设备的实验室。因此，这将是对加拿大最先进的光子基础设施的重要投资。

This application is for two infrared photodetectors and associated electronics that together enable individual photon events to be "time-tagged" with better than 1 nanosecond time resolution. This type of detection system is required in order to characterize the statistics of the photons from samples that emit in the infrared portion of the electromagnetic spectrum. The applicants have several funded research projects related to the development of novel optical sources in the infrared, and the requested equipment is required in order to quantify the unique properties that characterize these new sources. One of the main goals of the research is to demonstrate sources of light that are fundamentally quantum mechanical in nature, and that can be integrated into optical circuits fabricated on silicon wafers. Such light sources will be important for future information technologies based on quantum mechanical principles (such as the perfectly secure exchange of information, and possibly one day, quantum computation). There is very little related infrastructure in Canada: NRC in Ottawa is the only laboratory that, to the applicants' knowledge, has similar equipment to that requested here. As such, this would represent an important investment in state-of-the-art photonic infrastructure in Canada.
