Abstract

Superconducting nanowire single-photon detectors (SNSPDs) play a prominent role in sparse photon detection, but they tend to exhibit latching or saturation issues when confronted with high flux photons, which is commonly observed in applications such as deep space communication, LiDAR and passive imaging. Therefore, expanding the dynamic range of SNSPDs becomes indispensable. Inspired by the photoreceptor cells on human retina, this study conducted a biomimetic design of SNSPDs. The arrangement of pixels imitated the distribution of cone and rod cells, and the photosensitivity of these two different cells to the incident photons was altered by adjusting parameters such as linewidth, polarization, photosensitive area, and bias current. This design significantly enhances the overall dynamic range of the device, facilitating a linear response to incident photon flux ranging from 10 ³ photons/s to 1.16×10 ¹⁴ photons/s, and the dynamic range is 110.64 dB. Furthermore, imaging experiments using digital micromirror device (DMD) were performed to simulate high dynamic scenes. Combined with compressive sensing single pixel imaging strategy, imaging of incident light within a 90 dB range was achieved, demonstrating the functionality of the device over an extremely wide dynamic range.

高动态范围超导纳米线单光子探测器

超导纳米线单光子探测器（SNSPDs）在稀疏光子探测中发挥着重要作用，但当面对高通量光子时，它们往往会出现锁存或饱和问题，这在深空通信、激光雷达和被动成像等应用中很常见。因此，扩大snspd的动态范围势在必行。受人类视网膜感光细胞的启发，本研究进行了SNSPDs的仿生设计。像素的排列模拟了锥细胞和杆状细胞的分布，并通过调整线宽、极化、光敏面积和偏置电流等参数来改变这两种细胞对入射光子的光敏性。该设计显著提高了器件的整体动态范围，使器件对入射光子通量的线性响应范围从103光子/s到1.16×1014光子/s，动态范围为110.64 dB。此外，利用数字微镜装置（DMD）进行了模拟高动态场景的成像实验。结合压缩感知单像素成像策略，实现了90 dB范围内的入射光成像，展示了该设备在极宽动态范围内的功能。

期刊介绍： Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
