“…However, it should be borne in mind that the practical implementation of such a system may encounter an economic limitation in the form of a much higher cost per unit of optical power compared to the case of a wavelength of 975 nm. In addition, there are also likely to be limitations on the efficiency of light-to-electricity conversion of photovoltaic converters during the transition from silicon to converters based on gallium antimonide, although significant progress has been made recently in their development and commercial production [17]. Another way to increase the maximum cable length, while remaining in the spectral range of about 1 μm, requires to ensure a significant reduction in power consumption.…”

This paper describes experiments on having organized power transmission over optical fibers (Powerover- Fiber, PWoF) for a seismoacoutic seafloor module, consisting of a three-component geophone and a hydrophone. The experimental setup includes a fiber-optic information and energy cable, a photovoltaic optical energy converter, and seismic sensors based on intermolecular electron transfer. It is shown that the efficiency of the conversion depends on the optical power incident on the converter and load connected to it, so that optimal conversion regimes of operation are found out. The results of field tests of the experimental setup in the White Sea are also presented.

“…The most efficient PPCs to date are based on GaAs and absorb in the wavelength range of 800-850 nm [2], [16], [17], [18], [19], [20], [21], [22], yielding power conversion efficiencies up to 69% [16]. Other material systems have been explored for PPCs targeting operation at different wavelengths [2] such as 980 nm [23], 1064 nm [24], [25], [26], and 1550 nm [23], [27], [28], [29], [30]. For transmission through optical fiber, wavelengths in the telecommunications O-or C-bands (∼1310 or ∼1550 nm) offer reduced attenuation This work is licensed under a Creative Commons Attribution 4.0 License.…”

Photonic power converters (PPCs), which convert narrow-band light to electricity, are essential components in powerby-light systems. When designed for telecommunications wavelengths such as the O-band, near 1310 nm, the devices are wellsuited to power-over-fiber applications. Despite the potential for very high power conversion efficiencies (> 50%), PPCs can be adversely affected by high-intensity nonuniform illumination conditions. In this work, we characterized two O-band PPC designs based on: high-quality InGaAsP absorber material lattice-matched to an InP substrate, and metamorphic InGaAs absorber material lattice-mismatched to a GaAs substrate, a more cost-effective and scalable alternative. We measured each device under O-band laser illumination with five beam profiles having peak-to-average ratios ranging from 2 to 11. Both devices were insensitive to the beam uniformity for input illumination with average irradiance below 2 W/cm 2 over their 5.4-mm 2 active areas, but exhibited better open-circuit voltages under larger, more uniform illumination profiles at higher incident powers. Measured efficiencies reached 52.8% and 48.7% for the lattice-matched and mismatched devices, respectively. Distributed circuit modeling results suggested that both lateral conduction losses and localized heating effects were responsible for the measured dependence on beam-size. Our work demonstrates the potential for O-band PPCs, presenting two highly efficient designs suitable for powering devices requiring 250 mW, with an appropriate illumination profile.

“…To match the material band gap with the laser wavelength, numerous semiconductor materials have been used for different laser wavelength, such as GaAs for 808 nm laser light, InGaAs [7] and Si [8] for 1064 nm and GaInAsP [9] and GaSb [10] for 1550 nm. Among these materials, GaAs LPCs for converting the power of 808 nm laser light have attracted the most attention thanks to their well-characterized fabrication methods and high conversion efficiency [11−13] .…”

The gradient doping regions were employed in the emitter layer and the base layer of GaAs based laser power converters (LPCs). Silvaco TCAD was used to numerically simulate the linear gradient doping and exponential gradient doping structure, and analyze the transport process of photogenerated carriers. Energy band adjustment via gradient doping improved the separation and transport efficiency of photogenerated carriers and reduced the total recombination rate of GaAs LPCs. Compared with traditional structure of LPCs, the photoelectric conversion efficiency of LPCs with linear and exponential gradient doping structure were improved from 52.7% to 57.2% and 57.7%, respectively, under 808 nm laser light at the power density of 1 W/cm2.
