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.

“…MoS 2 quantum dots (QDs) are important nanostructures that have attracted attention over the years because of the high electrical conductivity [7], strong hydrogen absorption properties [8], and good biocompatibility [9]. In order to retain these characteristics when using a laser to synthesize QDs, one needs to control the temperature of the laser to allow for more stability in processing and more consistent power output [10,11].…”

Fabrication of transition metal dichalcogenide quantum dots (QDs) is complex and requires submerging powders in binary solvents and constant tuning of wavelength and pulsed frequency of light to achieve a desired reaction. Instead of liquid state photoexfoliation, we utilize infrared laser irradiation of free-standing MoS2 flakes in transmission electron microscope (TEM) to achieve solid-state multi-level photoexfoliation of QDs. By investigating the steps involved in photochemical reaction between the surface of MoS2 and the laser beam, we gain insight into each step of the photoexfoliation mechanism and observe high yield production of QDs, led by an inhomogeneous crystalline size distribution. Additionally, by using a laser with a lower energy than the indirect optical transition of bulk MoS2, we conclude that the underlying phenomena behind the photoexfoliation is from multi-photon absorption achieved at high optical outputs from the laser source. These findings provide an environmentally friendly synthesis method to fabricate QDs for potential applications in biomedicine, optoelectronics, and fluorescence sensing.
