    This review addresses the state-of-the-art of the mechanics of coated optical fibers. We discuss various mechanical problems in the analysis, design and reliability evaluations of polymer-coated or metallized optical fibers, including predictive modeling (mostly analytical), mechanical behavior of hermetic and non-hermetic coatings, adhesion and strippability problems, etc. The review is based primarily on the author's research conducted during his almost twenty-year tenure with Bell Laboratories, Basic Research, Murray Hill, New Jersey. The extension part concerns the application of a newly developed nanoparticle material (NPM) as an attractive substitute for the existing optical fiber coatings. The improvement over the existing knowledge-base is two-fold: 1) understanding of the role, objectives, challenges and approaches of structural mechanics in the design and reliability evaluations of coated optical fibers and fiber coatings; and 2) development (invention) of a new nano-particle material as an attractive substitute for the existing optical fiber coatings and, in some cases, of claddings as well. Some additional applications of the NPM are also addressed and briefly discussed.

    Speaker Biography:

    Dr. Ephraim Suhir is a Fellow of the IEEE, the ASME, the APS (American Physical Society) and the SPE (Society of Plastics Engineers). He has authored more than 250 technical publications (papers, book chapters, books, patents), including monographs Structural Analysis of Microelectronic and Fiber Optic Systems, Van-Nostrand, 1991 and Applied Probability for Engineers and Scientists, McGraw-Hill, 1997. Dr. Suhir received numerous distinguished service and professional awards, including the 2004 ASME Worcester Read Warner Medal for outstanding contributions to the permanent literature of engineering, 2001 IMAPS John A. Wagnon Technical Achievement Award, 2000 IEEE Outstanding Sustained Technical Contribution Award, 2000 SPE Fred O. Conley Award, and 1999 ASME and Pi-Tau-Sigma Charles Russ Richards Memorial Award for distinguished contributions to the areas of engineering encompassed by these professional societies and laying a foundation of a new discipline "Structural Analysis in Microelectronics and Photonics". Dr. Suhir is a member of the IEEE Technical Activities Board (TAB), and Distinguished Lecturer of the IEEE CPMT Society. He has presented numerous invited and keynote talks and taught many continuing education courses worldwide.
