“…Based on this study, a 21-m, 5.5 Gbps UWOC link with OFDM modulation was further demonstrated by Chen et al in 2017 [12]. The longest distance with a Gbps data rate UWOC system was demonstrated by Liu et al, who used a directly modulated 520-nm laser diode and a transmission distance of 34.5 m was achieved [13]. The recent advances of UWOC based on the visible light were summary in Fig.…”

This talk provides an overview of the latest underwater wireless optical communication (UWOC) research from the system to the device level. Besides, studies investigating underwater channel characterization are also described. OCIS codes: (060.4510) Optical communications; (250.0250) Optoelectronics; (040.5160) Photodetectors.Numerous human underwater activities, ranging from mineral resource exploiting to marine life discovery and even environment monitoring, creating huge demand of highly reliable, secured and high data rate underwater wireless communication systems, as shown in Fig. 1. Compared with radio-frequency (RF) and acoustic wave underwater communications, underwater wireless optical communications (UWOC) outperform in various aspect, such as unlicensed spectrum, large bandwidth (THz) [1] and low data latency.

“…The underwater wireless optical communication system link of 20 m based on 450 nm LDs using non-return-to-zero OOK (NRZ-OOK) modulation was proposed by Shen et al, 16 with a data rate of 1.5 Gbps. The measured bit error rate of the received NRZ-OOK data was 2.23 3 10 24 at 2.3 Gbps data rate in the experiment by Oubei et al 17 In the study of Liu et al, 18 a low-power 520-nm green LD-based underwater wireless optical communication system was experimentally demonstrated to implement maximal communication capacity of up to 2.7 Gbps over a 34.5-m underwater transmission distance using NRZ-OOK modulation. Recently, underwater wireless laser communication systems with higher data rates were achieved by employing complex modulation schemes, such as orthogonal frequency-division multiplexing (OFDM) including quadrature amplitude modulation (QAM).…”

In this article, we propose the demonstration of an underwater wireless laser communication link operating at data rates of up to 100 Mbps over a band-limited turbid water channel using a modified pulse position modulation scheme with a sloped pulse. The communication link uses an avalanche photodiode module as the receiver. The bit error rate of a 5.4 3 10 26 by 450-nm blue laser diode in turbid water with 1.4 Nephelometric Turbidity Unit was below the forward error correction limit. Our demonstrated underwater wireless laser communication system is simple to use and maintains a high data transmission rate.

“…Given these inherent drawbacks in RF and acoustic channels, underwater wireless optical communications (UWOC) turns out to be an appropriate solution for real-time high-data-rate communication at giga-bits-per-second over 20 meters [8][9][10]. Moreover, in the industry, the underwater transmission distance has been extended over 150 m with a data rate of 12.5 Mbps, as demonstrated by Sonardyne's BlueComm 200 system.…”

Abstract:For circumventing the alignment requirement of line-of-sight (LOS) underwater wireless optical communication (UWOC), we demonstrated a non-line-of-sight (NLOS) UWOC link adequately enhanced using ultraviolet (UV) 375-nm laser. Path loss was chosen as a figure-of-merit for link performance in this investigation, which considers the effects of geometries, water turbidity, and transmission wavelength. The experiments suggest that path loss decreases with smaller azimuth angles, higher water turbidity, and shorter wavelength due in part to enhanced scattering utilizing 375-nm radiation. We highlighted that it is feasible to extend the current findings for long distance NLOS UWOC link in turbid water, such as harbor water.
