该论文提出了一种基于CMOS单光子雪崩二极管（SPAD）的可见光通信接收器，实现了500Mb/s的数据速率和-46.1dBm的灵敏度，解决了激光二极管可见光通信中高灵敏度、高速接收的难题。
Kingdom 3 Photon Force, Edinburgh, United Kingdom 1 2 III-nitride laser diodes (LDs) are promising sources for light fidelity (LiFi) networks, underwater wireless optical communications (UWOC), and plastic optical fiber (POF) communications [1] due to their high modulation bandwidths (>5GHz) compared to LEDs (<20MHz). Their narrow linewidths also enable robust free-space Gb/s LiFi links in the presence of high intensities of sunlight through selective spectral filtering. Fully integrated CMOS visible light communications (VLC) receivers have recently been developed to enable miniaturised and low cost Gb/s LD-based links [2]. Sensitivity of these devices is constrained by electrical noise sources such as thermal, shot or excess noise related to the employment of PIN photodiodes (PDs) or linear
