Dr. Pamela McNamara of the University of Sydney shall give a talk entitled, “Guiding Light: The Making of Optical Fibers” on November 18, 2011 at 4:30-6:00 p.m. at Room 318 of the Padre Faura Hall in Ateneo de Manila University.

Dr. Pamela McNamara is with the Australian Centre for Microscopy and Microanalysis (ACMM) and the Institute of Photonics and Optical Science (IPOS), School of Physics University of Sydney, NSW, Australia. She is also with the Materials Engineering, Monash University, Melbourne, Vic, Australia Centre for Telecommunications and Micro-Electronics, Victoria University, Melbourne, Australia.

Abstract

For about 20 years, between 1989 and 2009, the Optical Fibre Technology Centre (OFTC), a multi-disciplinary, research-only department of the University of Sydney, was one of the world’s centres for fabrication of specialty optical fibres.

Optical fibres are flexible light guides. They can be made from any material which is transparent to the wavelength of interest and which can be drawn into hair-thin filaments that are strong enough to be handled. OFTC made fibres in silica-based glasses, fluoride glasses and acrylic polymer, in both solid and holey fibre designs. Internal structures in optical fibres are used to confine light within the fibre and also produce a variety of special effects for applications in telecommunications, sensing, medicine, defence and astronomy. These structures are usually ideal theoretical constructs which may be difficult to make in practice. Many techniques are used in the production of optical fibres, such as Modified Vapour Chemical Deposition, casting, extrusion and ultrasonic drilling. Some fibre designs are dictated by what is physically possible. Every material and technique comes with its own set of problems and real fibres often have characteristics very different from those intended by their designers.

This talk explores the many problems that arise in optical fibre fabrication, how they may affect the performance of the fibres and how some of them can be overcome by application of scientific knowledge and ingenuity.
