“…As water is relatively transparent to blue or green light [2], laser or LED based UWOC technology has attracted much attention as a more promising solution in close range high-capacity underwater communication scenarios [3][4][5][6][7]. However, charging the batteries in UWOC systems in underwater scenarios is usually very expensive and impractical [8], and a promising solution is energy harvesting by UWOC systems, further proposed in [9][10][11][12][13][14][15][16][17] as the SLIPT technique, in which the light signals received by solar cells are used for energy harvesting (EH) and information decoding (ID).…”

Charging batteries in underwater scenarios is generally very expensive and impractical, and solar cell (SC)-based underwater simultaneous lightwave information and power transfer (SLIPT) systems are a powerful solution. However, silicon SC receiver devices have limited bandwidth and are prone to deep signal-to-noise (SNR) degradation during underwater light fading effects. For these problems, this manuscript proposes a negative-biased SC optical receiver scheme to increase the -3dB bandwidth of silicon SC from 440 kHz to 780 kHz. For the deep fading of SNR caused by various degradation effects in the water environment, a low peak average power ratio (PAPR) discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) modulation scheme is employed to counteract the deep fading phenomenon in the system. Achieved a communication rate of 15.2 Mbps in a 60cm underwater environment with a fading factor of 0.403 and a bit error rate (BER) of 1.59 × 10 −3 under perturbation. Also, the performance of DFT-S-OFDM and orthogonal frequency division multiplexing (OFDM) modulation systems in water environments with different turbidity (absorption characteristics and scattering) and presence of disturbances are compared separately, and the DFT-S-OFDM system is more robust. Finally, we complete the energy harvesting during the communication process, and the experiments show that the total battery power efficiency of the energy harvesting system can be increased by 1.87 times under the white light-emitting diode (LED) continuous irradiation for three hours.

“…On the other hand, the power-splitting method is based on separating the received signal's power into alternating current (AC) and direct current (DC) components for information decoding (ID) and charging, respectively. Finally, in a spacesplitting approach, multiple transmitters transfer either energy or information to the corresponding receivers for EH or ID [10], [11]. In the UWOC systems with SLIPT capability, a solar panel-based receiver for EH and ID is used [12].…”

“…Although the charging time for EH was considered in the mentioned work, no approach was proposed to decrease it. However, in [11] the optimization of the splitting factor (either in time or power) in terms of harvested energy while satisfying BER and spectral efficiency constraints was analyzed. In addition, closed-form equations were derived for the average harvested energy, BER, and spectral efficiency under the presence of underwater turbulence, which was modeled using a log-normal distribution.…”

The energy consumption of the Internet of underwater things (IoUT) nodes is a capital aspect that dramatically affects the applicability of wireless optical technologies in several scenarios, such as ocean monitoring or underwater sensor networks. Simultaneous lightwave information and power transfer (SLIPT) is a cost-effective and energy-efficient solution for energy-constrained wireless systems. Nonetheless, the reported battery-charging times for underwater operations are high, which should be improved to make this technology attractive enough to be considered for actual implementations. This paper provides a new SLIPT strategy, introducing a specific optical signal transmission scheme by controlling the transmitted direct current (DC) level component. The scheme is based on a DC-On Off Keying (OOK) modulation with an adjustable signal range (SR) to improve the energy-harvesting process and battery-charging time for underwater operations. The results reveal that the system provides a signal-to-noise ratio higher than 28 dB and the bit-error rate of less than 10 −10 which is below the forward error correction limit with improved charging time around 30 minutes and 15 seconds for 5 F and 9.4 mF, respectively over 20 cm, and 63 seconds for 9.4 mF in 50 cm link distance.INDEX TERMS Underwater wireless optical communications, energy harvesting, information decoding, simultaneous lightwave information and power transfer (SLIPT), Internet of underwater things (IoUT).
