AI 中文摘要
周边栅控单光子雪崩二极管（pg-SPADs）具备动态暗噪声调制能力，已有研究表明其在连续光照下会以噪声为代价换取光子灵敏度，但该权衡关系在脉冲光学系统中的影响此前尚未被研究。本研究填补了这一空白，展示了采用0.35μm标准CMOS工艺制备的pg-SPADs会以脉冲探测效率为代价，降低突发窗口内虚假事件的扩散，基于观测到的权衡关系，本文提出了脉冲激光雷达（LIDAR）应用中pg-SPADs的最优使用指南。
英文摘要
Perimeter-gated single-photon avalanche diodes (pg-SPADs) are known for their dynamic dark noise modulation capabilities. They are reported to trade noise for photon sensitivity under continuous illumination. However, the implications of this trade-off have not heretofore been studied with pulsed optical systems. This work bridges this gap. We demonstrate that pg-SPADs fabricated in a 0.35 $μ$m standard CMOS process trade-off pulse detection efficiency for a reduction in the the spread of spurious events within a burst window. Consequently, herein, we propose guidelines for the optimal use of pg-SPADs in pulsed LIDAR applications in view of the observed trade-off.
