“…In addition, LDs provide more wavelength options in the PoF system spectrum, ranging from 780 to 1650 nm for connection with optical fiber compared with any other light sources such as LED. Additionally, fiber lasers are also used as a light source; however, degradation of the cladding caused by high /power or the power stability remains unsolved an issue 30 …”

“…InGaAs and GaSb have the same energy gap and the output voltage level of 0.7 eV and 0.5 V, respectively 7 . The efficiency of these materials for PoF mechanism in different experiments were reported; Si has a maximum efficiency of 42.9% at 980 nm, 54 whereas InGaAs and GaSb have 45% and 49% peak efficiency at 1550 nm 30 and 1680 nm 55 respectively. GaAs is a good material for PV since it has a direct and large bandgap material and has high tolerance over a wide range of temperatures.…”

“…However, Si can still be a promising material for PPC applications, with a conversion efficiency of up to 40% at 850 nm wavelength, and apparently has low manufacturing cost. Besides that, different efficiency levels for GaAs cells have been reported mostly due to GaAs-based power converters’ output voltage can be increased by interconnecting converter segments or multijunction PV cells 30 . While InGaAs and GaSb have output voltage levels lower than GaAs, 0.5 V, which is too low to supply power to any devices.…”

Conventional electricity distribution using copper wires is well established due to its high efficiency. However, recent research and development on power-over-fiber (PoF) has proposed optical fiber as an alternative to copper wire as the transmission medium for electricity distribution. The research and development on PoF technology have gained significant momentum over the past decade due to its advantage over copper cables in providing electrical isolation and reducing space in remote sites. The technological advances in laser diodes, fiber optic cable fabrications, and semiconductor manufacturing contribute to developing an efficient PoF system, making them more commercially viable. This paper reviews various PoF systems that imply different arrangements of high-power lasers, fiber optic cables, and photovoltaic power converters. The PoF systems are made available for various applications such as in-home applications, smart power management, and powering sensors with bidirectional communications. The comparison of the PoF composition, commercialized PoF systems, and patented PoF systems are also comprehensively discussed. Finally, the challenges in implementing PoF systems are highlighted, as well as future prospects for research and applications. The information reviewed in this paper aims to provide a roadmap for developing a future PoF system with improved power conversion efficiency.

Power-over-fiber (PoF) is a novel power transmission technology that uses optical fibers, instead of the traditional copper wires, to deliver electrical power to feed remote sensors or electrical devices. Research on the PoF systems has been receiving extensive attention due to the advantages of fiber optic systems compared to the conventional power supply systems. Optical fibers are less bulky and lightweight, robust to electromagnetic interference (EMI) and electric sparks, resistant to corrosion and to extreme weather. Optical fiber installation is less susceptible to explosive and hazardous environments and presents a minimal security risk. Moreover, a single optical fiber can simultaneously transmit highspeed data and deliver electrical power to remote places. This paper experimentally demonstrates a PoF system using offthe-shelf components to feed microelectronics for low-power applications. The optical system consists of a 1550nm Pigtailed Laser Diode, an InGaAs photodetector for the optical to electrical conversion, and both Single-Mode (SM) and Multi-Mode (MM) optical fibers are tested. Experimental results show that data signal and power signal can be successfully transmitted simultaneously using an optical communication link. Analysis of the electrical-to-optical (E/O) conversion efficiency of the laser source, optical-to-optical (O/O) efficiency of the optical fibers, and optical-to-electrical (O/E) conversion efficiency of the receiver are also presented. Moreover, the System Energy Efficiency (SEE) is studied, and the effects of signal data-rate on the SEE are investigated.
