摘要

光电倍增管探测器具有极高的灵敏度，近年来作为光接收机的一部分应用于水下无线光通信(UWOC)的研究。但其动态功率范围较低，严重制约了光接收机性能的提高。本文提出了一种基于液晶光阀(LCLV)和光电倍增管(PMT)增益控制的自适应光功率控制(AOPC)系统，并进行了验证，以提高高灵敏度UWOC链路的光动态范围。实验结果表明，在传输速率为100 Mbps的情况下，加载自适应接收端光功率控制功能后，接收模块的光信号动态范围扩大了68dB。

High Speed Underwater Wireless Optical Communication with High Receiver Sensitivity and Large Dynamic Range

Photomultiplier tube (PMT) detector, with extreme sensitivity, has been applied as a part of optical receiver in underwater wireless optical communication (UWOC) research in recent years. However, it suffers low dynamic power range, which significantly restricts the increase of optical receiver performance. In this paper, an adaptive optical power control (AOPC) system based on liquid crystal light valve (LCLV) and photomultiplier tube (PMT) gain controlling is proposed and demonstrate to increase the optical dynamic range for high sensitive UWOC links. Experimental results show under the transmission rate of 100 Mbps, the optical signal dynamic ranges of receiver module after loading the adaptive receiver-side optical power control function expands 68dB.
