在这项工作中,我们实验证明了水下无线光通信(UWOC)的链接超过2.96米的距离与两个445 nm的光纤尾激光二极管采用轨道角动量(OAM),以允许空间复用。使用开关键控、不归零(OOOK-NRZ)调制方案,在水中实现了3 Gbit/s的数据速率,衰减系数为0.4128 m(-1),平均误比特率(BER)为2.073 x 10(-4),远低于前向纠错(FEC)阈值。(C)2016美国光学学会
In this work we experimentally demonstrated an underwater wireless optical communications (UWOC) link over a 2.96 m distance with two 445-nm fiber-pigtailed laser diodes employing Orbital Angular Momentum (OAM) to allow for spatial multiplexing. Using an on-off keying, non-return-to-zero (OOK-NRZ) modulation scheme, a data rate of 3 Gbit/s was achieved in water with an attenuation coefficient of 0.4128 m(-1) at an average bit error rate (BER) of 2.073 x 10(-4), well beneath the forward error correction (FEC) threshold.
