Download or read book L Band Bismuth Based Erbium Doped Fibre Amplifier written by Wu Yi Chong and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization study of Bismuth-based Erbium-doped Fibre (Bi-EDF) and its performance as gain medium for L-band Erbium-doped Fibre Amplifier (EDFA) is studied. Bismuth oxide glass host enables very high erbium doping concentration without significant concentration quenching effect. The Bi-EDF studied is only 2.15m long with Erbium ion concentration of 3,250 wt. ppm. corresponding to a maximum absorption coefficient of 157.61dB/m at 1530nm. With optimum excitation, Bi-EDFA exhibits small signal gain bandwidth of over 70nm ranging from 1550nm to 1620nm. Maximum signal gain per length coefficient at 1580nm for Bi-EDFA is 12.7dB/m. A 56nm 3dB gain bandwidth with average gain of 18.6dB is achieved. Improvement on the small signal gain performance of Bi-EDFA is demonstrated in a two-stage EDFA configuration. By utilizing C-band ASE generated by Bi-EDFA as pump source for a second stage EDF, maximum small signal gain improvement of 5.0dB over the single stage Bi-EDFA is observed.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive contributed volume that aims to describe and explain the design, fabrication, operating characteristics, and specific applications of the most popular and useful types of specialty optical fibers. These "specialty fibers include any kind of optical fiber that has been architecturally manipulated to diverge from a conventional structure. For instance, metal-coated fibers can be utilized for bandwidth improvement, and hollow core fibers offer more controllable dispersion for sensitive medical procedures. Applications for these specialty fibers abound in the biomedical, sensors, and industrial fields, as well as in more traditional communications capacities. This book will act as a specialty fiber "guided tour, hosted by the top names in the discipline. The globally renowned editors, Drs. Mendez and Morse, have extensive experience in research, academia, and industry.*Completely covers biomedical and industrial sensor technology with emphasis on real world applications *Comparative studies of pros and cons of all fiber types with relation to test and measurement, mechanical properties and strength, and reliability*Easy to access essential facts and details at the begining of each chapter

Download or read book Optical Fibers Research Advances written by Jürgen C. Schlesinger and published by Nova Publishers. This book was released on 2007 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: An optical fibre is a glass or plastic fibre designed to guide light along its length by confining as much light as possible in a propagating form. In fibre with large core diameter, the confinement is based on total internal reflection. In smaller diameter core fibres, (widely used for most communication links longer than 200 meters) the confinement relies on establishing a waveguide. Fibre optics is the overlap of applied science and engineering concerned with such optical fibres. Optical fibres are widely used in fibre-optic communication, which permits transmission over longer distances and at higher data rates than other forms of wired and wireless communications. They are also used to form sensors, and in a variety of other applications. The term optical fibre covers a range of different designs including graded-index optical fibres, step-index optical fibres, birefringent polarisation-maintaining fibres and more recently photonic crystal fibres, with the design and the wavelength of the light propagating in the fibre dictating whether or not it will be multi-mode optical fibre or single-mode optical fibre. Because of the mechanical properties of the more common glass optical fibres, special methods of splicing fibres and of connecting them to other equipment are needed. Manufacture of optical fibres is based on partially melting a chemically doped pre-form and pulling the flowing material on a draw tower. Fibres are built into different kinds of cables depending on how they will be used. This new book presents the latest research in the field.

Download or read book Handbook of Radio and Optical Networks Convergence written by Tetsuya Kawanishi and published by Springer Nature. This book was released on 2024-11-04 with total page 1711 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides comprehensive knowledge on device and system technologies for seamlessly integrated networks of various types of transmission media such as optical fibers and millimeter and THz waves to offer super high-speed data link service everywhere. The seamless integration of the knowledge of radio and optical technologies is needed to construct wired and wireless seamless networks. High-frequency bands such as millimeter-wave and THz-wave bands where super wideband spectra are available can offer high-speed data transmission and high-resolution sensing. However, the expected coverage is limited due to large wave propagation loss. Thus, convergence of radio and optical links is indispensable to construct worldwide networks. The radio and optical technologies share the same physics and are closely related to each other but have been developed independently. Therefore, there is a big gap between these two fields. Bridging the two fields, this handbook is also intended as a common platform to design integrated networks consisting of wireless and wired links. Full coverage of wireless and wired convergence fields ranging from basics of device and transmission media to applications allows the reader to efficiently access all the important references in this single handbook. Further, it also showcases state-of-the-art technology and cases of its use.
