Abstract

Recent state-of-the-art for ultra-highly Yb-doped silica-based fibers have been presented. Detailed properties of the developed fibers, i.e. refractivity of different co-dopants, background loss behavior due to Yb-doping, photodarkening effects and lasing efficiency degradation at high Yb concentrations have been studied. Application of highly Yb-doped fibers for obtaining of lasers and amplifiers of an extremely shot lengths have been discussed. Novel results regarding development of ultra-highly Yb-doped large-mode-area (LMA) fiber amplifier have been presented.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
