Underwater 6.4-m Optical Wireless Communication with 8.8-Gbps Encoded 450-nm GaN Laser Diode

Abstract

6.4-m underwater optical wireless communication based on a GaN blue laser diode under direct 8.8-Gbps QAM-OFDM encoding is demonstrated with an average signal-to-noise ratio of 16 dB and a bit error rate of 3.8 x 10(-3).
