摘要

光子数量分辨探测器（PNRD）是一种能够测量入射光束中存在的光子数量的设备，可对光源进行量子级测量和表征。本文探讨了集成在单模波导上的线性复用光子数量分辨单光子探测器阵列的性能和设计考虑因素。我们的研究重点是定义和分析这种阵列在各种条件下的保真度，并提出实现这种阵列的实用设计。通过理论分析和数值模拟，我们展示了传播损耗和暗计数如何对系统性能产生重大影响，并强调了在实际应用中减轻这些影响的重要性。

Linearly multiplexed Photon Number Resolving single-photon detectors array

Photon Number Resolving Detectors (PNRDs) are devices capable of measuring the number of photons present in an incident optical beam, enabling light sources to be measured and characterized at the quantum level. In this paper, we explore the performance and design considerations of a linearly multiplexed photon number-resolving single-photon detector array, integrated on a single mode waveguide. Our investigation focus on defining and analyzing the fidelity of such an array under various conditions and proposing practical designs for its implementation. Through theoretical analysis and numerical simulations, we show how propagation losses and dark counts may have a strong impact on the performance of the system and highlight the importance of mitigating these effects in practical implementations.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
