“…The SPC with four pump input fibers at a coupling efficiency of 90%, low loss, and excellent signal feed-through properties has comparable performance characteristics to components based on standard step-index fibers for signal feed-through (c.f. reference 13 ). This was enabled by altering the cladding shape of the CCC-fiber along a section of 20 mm (required for SPC manufacturing) with the presented CO 2 -laser ablation process.…”

“…Generally speaking, the technical scope and fabrication complexity of SPCs are relatively larger than PCs; hence the brief overview of power scaling advances in this section mainly focuses on SPCs. Most of the fabrication processes or technical details are similar for both the SPCs and PCs, and more details on the fabrication techniques or research progress can be found in other review articles [152,153].…”

The success of high-power fiber lasers is fueled by maturation of active and passive fibers, combined with the availability of high-power fiber-based components. In this contribution, we first overview the enormous potential of rare-earth doped fibers in spectral coverage and recent developments of key fiber-based components employed in high-power laser systems. Subsequently, the emerging functional active and passive fibers in recent years, which exhibit tremendous advantages in balancing or mitigating parasitic nonlinearities hindering high-power transmission, are outlined from the perspectives of geometric and material engineering. Finally, novel functional applications of conventional fiber-based components for nonlinear suppression or spatial mode selection, and correspondingly, the high-power progress of function fiber-based components in power handling are introduced, which suggest more flexible controllability on high-power laser operations.

Power-over-fiber (PWoF) is an attractive technology for transmitting power utilizing optical fibers. Because optical fibers are nonconductive power lines, and can transmit data signals simultaneously, PWoF enables us to provide usages that are not feasible with conventional electric power supply systems using copper wires. This study presents an overview of PWoF using various types of optical fibers, and introduces a practical application for powering remote antenna units (RAUs) in mobile communications. To power a RAU, the author's group has worked on PWoF using double-clad fibers, which comprise a single-mode core and an inner cladding that surrounds the core. The core structure is more suitable for simultaneous high-speed data signals and high-power feed light transmission than other optical fibers. To demonstrate the feasibility, the experimental demonstrations of the authors' group are introduced in detail. In addition, the latest performance comparison of PWoF reported so far is presented, and future prospects are described. Index Terms-Double-clad fiber (DCF), mobile communications, optical power transmission, photovoltaic power converter (PPC), power-over-fiber (PWoF), radio-over-fiber (RoF), remote antenna unit (RAU). I. INTRODUCTIONW ITH the rapid development of mobile communication technologies, radio-over-fiber (RoF) has become essential for achieving higher capacity data communications [1]−[3]. It is desirable for remote antenna units (RAUs) to provide wireless communication with mobile terminals over optical fibers in all types of locations, and thus RAUs require operational technologies that can be adapted to various installation environments. In addition, as the carrier frequency of radio-frequency signals increases and cell size decreases, more RAUs with simpler installation techniques will be required.Electric power is always required for communication. In main communication facilities such as network nodes and central offices (COs), it is relatively easy to utilize commercial power supply facilities because they are installed in office areas and densely populated areas where infrastructure facilities are well Manuscript
