水下无线光通信(UWOC)是一种利用可见光在水下环境中传输数据的无线通信技术，有着广泛的应用前景。基于提离(In，Ga)N纳米线，提出并成功制备了一种具有良好透过率的自供电光电化学(PEC)光电探测器(PD)。Pd的透明功能是360°全方位水下探测的关键，这是通过将(In，Ga)N纳米线从不透明的外延衬底分离到铟锡氧化物(ITO)/玻璃上实现的。实验还发现，SiO_2绝缘层可以使光电流提高约12倍。纳米线的核壳结构有利于载流子的产生和光电流的贡献。在此基础上，建立了一个ASCII码的通信系统，对水下通信中的局部放电检测进行了演示。该工作为360°全向PDS在UWOC系统和水下光探测中的广泛应用提供了一条有效途径。
Underwater wireless optical communication (UWOC) is a wireless communication technology using visible light to transmit data in an underwater environment, which has wide applications. Based on lift-off (In,Ga)N nanowires, this work has proposed and successfully demonstrated a self-powered photoelectrochemical (PEC) photodetector (PD) with excellent transmissivity. The transparent functionality of the PD is critical for 360° omnidirectional underwater detection, which was realized by detaching the (In,Ga)N nanowires from the opaque epitaxial substrates to the indium tin oxide (ITO)/glass. It was also found that the insulating SiO2 layer can enhance the photocurrent by about 12 times. The core–shell structure of the nanowires is beneficial for generating carriers and contributing to the photocurrent. Furthermore, a communication system with ASCII code is set to demonstrate the PD detection in underwater communication. This work paves an effective way to develop 360° omnidirectional PDs for the wide applications in UWOC system and underwater photodetection.
