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

Book excerpt: A number of military systems incorporating fiber optics require long lengths of high strength fibers. These fibers, like other silicate derived glasses, suffer from the phenomenon of stress corrosion or static fatigue. The observed fatigue occurs when fibers are subject to tensile stresses in a humid environment. None of the currently used organic buffer and overcoating materials is impermeable to water and, therefore, to provide hermetic protection, one must look to other materials. Among the more promising materials are metals, silicon nitride, and diamond-like carbon. The requirements and possible behavior of suitable coatings will be discussed in terms of performance, expected reliability, and economic considerations.

Book excerpt: A method for forming hermetic coatings on optical fibers by hot filament assisted chemical vapor deposition advantageously produces a desirable coating while maintaining the pristine strength of the pristine fiber. The hermetic coatings may be formed from a variety of substances, such as, for example, boron nitride and carbon.

Book excerpt: This program addresses the military and commercial needs for strong optical fibers having a high degree of durability. The approach to solving this problem is to demonstrate the feasibility of producing hermetically coated fibers, coating with a suitable hermetic barrier, proof testing, optical and mechanical characterization, and analysis of results. The hermetic coating system has been designed to coat fibers which have previously been drawn. Materials evaluated as hermetic coatings included ion deposited carbon, tin, and indium. Initial results indicate that the ion deposited forms of carbon and indium alone or in combination appear to provide the best compromise of coating properties, while not degrading fiber strength. The long range objective of this program is to produce fibers with 1-7 db per kilometer attenuation at 850 nanometers, proof tested in excess of 100,000 psi, in lengths of 10-30 kilometers. It is anticipated that after hermetic coating, these optical waveguides will exhibit a 95% probability of survival in moist environments when subjected to a 2% continuous strain over periods up to 10 years.
Download or read book Low Speed Carbon Deposition Process for Hermetic Optical Fibers written by and published by . This book was released on 1999 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: For optical fibers used in adverse environments, a carbon coating is frequently deposited on the fiber surface to prevent water and hydrogen ingression that lead respectively to strength degradation through fatigue and hydrogen-induced attenuation. The deposition of a hermetic carbon coating onto an optical fiber during the draw process holds a particular challenge when thermally-cured specialty coatings are subsequently applied because of the slower drawing rate. In this paper, we report on our efforts to improve the low-speed carbon deposition process by altering the composition and concentration of hydrocarbon precursor gases. The resulting carbon layers have been analyzed for electrical resistance, Raman spectra, coating thickness, and surface roughness, then compared to strength data and dynamic fatigue behavior.
