Retina-Inspired 2D Semiconductor NIR Sensor with PRO Architecture for Photodetection.

ABSTRACT: Light detection and ranging (LiDAR) technology is critical for autonomous driving, which relies on abundant near-infrared (NIR) photodetectors to accurately capture three-dimensional spatial information. CMOS-based LiDAR detection systems are less efficient with respect to computational efficiency, inherently limited by their von Neumann architecture, leading to high latency and significant computational demands. Retina-inspired neuromorphic sensors integrated from sensing and computation present a promising alternative but need additional analog-to-digital converters (ADCs). Here we present the photosensitive ring oscillator (PRO) based visual afferent neuro-biosensors for LiDAR-based sensing applications. The PRO employs monolayer MoS₂ as channels decorated by Nd³⁺/
