基于红（R）、绿色（G）和蓝色（B）光的水下无线光通信（UWOC）的可用性使得RGB波分复用（WDM）UWOC系统的实现成为可能。通过适当地混合RGB光以形成白色光，WDM UWOC系统在同时进行水下照明和高速通信方面具有突出的潜力。在这项工作中，第一次，我们实验证明了一个9.51-Gb/s的WDM UWOC系统使用红色发光的激光二极管（LD），单模尾纤绿色发光的LD和多模尾纤蓝色发光的LD。通过采用32正交幅度调制（QAM）正交频分复用（OFDM）调制的演示，红光，绿光和蓝光LD成功地传输信号的数据速率分别为4.17 Gb/s，4.17 Gb/s和1.17 Gb/s，在10米的水下信道。相应的误码率（BER）分别为2.2 x 10（-3）、2.0 x 10（-3）和2.3 x 10（-3），低于3.8 x 10（-3）的前向纠错（FEC）阈值。(C)2017美国光学学会
The availability of the underwater wireless optical communication (UWOC) based on red (R), green (G) and blue (B) lights makes the realization of the RGB wavelength division multiplexing (WDM) UWOC system possible. By properly mixing RGB lights to form white light, the WDM UWOC system has prominent potentiality for simultaneous underwater illumination and high-speed communication. In this work, for the first time, we experimentally demonstrate a 9.51-Gb/s WDM UWOC system using a red-emitting laser diode (LD), a single-mode pigtailed green-emitting LD and a multi-mode pigtailed blue-emitting LD. By employing 32-quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) modulation in the demonstration, the red-light, the green-light and the blue-light LDs successfully transmit signals with the data rates of 4.17 Gb/s, 4.17 Gb/s and 1.17 Gb/s, respectively, over a 10-m underwater channel. The corresponding bit error rates (BERs) are 2.2 x 10(-3), 2.0 x 10(-3) and 2.3 x 10(-3), respectively, which are below the forward error correction (FEC) threshold of 3.8 x 10(-3).
