Experimental and theoretical studies of the optical properties of large core step index (SI) plastic optical fibers (POF) and graded index (GI) POFs are reported. A set of criteria and analyses of physical parameters are developed in context to the major issues of POF applications in short-distance communication systems. Analyses are presented to show how the measured POF optical attenuation affects the overall performance in wavelength division multiplexing (WDM) and how use of perfluorinated polymers can overcome limitation inherent to current POF materials. Results of POF optical bandwidth measurements by direct picosecond time domain methods are reported and their relationship to refractive index profiles theoretically analyzed by the WKB and finite-element methods. Two high-resolution optical techniques of refracted near-field and transverse interferometric methods are presented and used to measure the index profiles of large core POFs. Results reveal that the index profile of current GI POF is not parabolic, but consists of two markedly different regions. Analysis of the index profile reveals that strong mode coupling increases the GI POF bandwidth from its profile-determined value of 0.43 GHz to its measured value of 3.0 GHz for 100m. We further study mode coupling effect inside POFs through various experimental techniques, including pulse broadening-length dependence measurements and far-field radiation pattern measurements.
Polymer Optical Fibres: Fibre Types, Materials, Fabrication, Characterization, and Applications explores polymer optical fibers, specifically their materials, fabrication, characterization, measurement techniques, and applications. Optical effects, including light propagation, degrading effects of attenuation, scattering, and dispersion, are explained. Other important parameters like mechanical strength, operating temperatures, and processability are also described. Polymer optical fibers (POF) have a number of advantages over glass fibers, such as low cost, flexibility, low weight, electromagnetic immunity, good bandwidth, simple installation, and mechanical stability.

Optische Eigenschaften wie Bandbreite und Leitungsverluste werden diskutiert, ebenso Ausbreitungscharakteristika und deren Einfluss auf die Leistungsmerkmale der Fasern. Im zweiten Teil werden unterschiedliche Methoden der Herstellungs und Charakterisierung präsentiert. Mit Bezug zu den technischen Anforderungen der optischen Kommunikation konzentriert sich das letzte Kapitel auf die Vorteile und Einsatzmöglichkeiten von polymeren optischen Fasern.
Plastic or polymer optical fibers (POF) have emerging applications in communication systems. This chapter provides a general overview of the different types of POF existing at both a research and a commercial level. This chapter also discusses in detail the types of POF that are currently the most widely adopted for communications applications. Topics include material sets such as PMMA, step and graded indices POF, and the fiber’s properties including bend radius, mechanical performance, attenuation, and dispersion. POF link designs are considered, including sources and receivers, as well as link budget design considerations. Examples of commercially available products are discussed as well as speculation on future developments in the field.
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
