摘要

单光子雪崩二极管(SPAD)对基于光子的测量和计量至关重要,它可以在几个光子的水平上进行测量比较,并促进全球溯源至 SI。空间均匀的探测器响应对这些应用至关重要。在此,我们报告了市售硅 SPAD 中的干扰效应,这种效应不利于其空间均匀性。观察到的对比度高达 18%,这给利用相干光和要求稳定检测效率的计量和一般应用带来了问题。我们将器件光学窗口排除在外,将可能的原因隔离到抗反射涂层、半导体表面和 SPAD 内部结构之外。我们还展示了通过将入射光束对准最大建设性干扰位置来利用这种次优行为的结果,结果显示有效检测效率为 51.1(1.7)%,而在干扰被抑制的情况下,正常值为 44.3(1)%。我们预计,这项工作将对这些设备的持续发展、表征这些设备的方法及其在精确测量中的应用产生重大影响。

Interference effects in commercially available free-space silicon single-photon avalanche diodes
Single-photon avalanche diodes (SPADs) are essential for photon-based measurements and metrology, enabling measurement comparisons at the few-photon level and facilitating global traceability to the SI. A spatially uniform detector response is crucial for these applications. Here, we report on interference effects in commercially available silicon SPADs that are detrimental to their spatial uniformity. Contrasts as high as 18% are observed, posing problems for metrology and general applications that utilize coherent light and require stable detection efficiencies. We eliminate the device optical window as a contributing interface, isolating likely causes to anti-reflective coatings, the semiconductor surface, and the SPAD's internal structure. We also present results where we leverage this sub-optimal behavior by aligning an incident beam with the position of maximum constructive interference, yielding an effective detection efficiency of 51.1(1.7)% compared to the normal value of 44.3(1)% obtained with the interference suppressed. We anticipate that this work will significantly impact the continuing development of these devices, the methods for characterizing them, and their use in accurate measurements.

期刊介绍: Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
